I am experimenting with Jenkins and Ant. I would like to simply run my Makefile that does everything, the build and the tests.
I figured out that the best way is to use Ant because I become flexible with my build process similarly to travis.yml.
Unfortunately the compiler I am using only exists on Windows so I installed Jenkins on Windows. I wrote this build.xml
<?xml version="1.0"?>
<project name="Hello World Project" default="info">
<target name="info">
<echo>Hello World - Welcome to Apache Ant!</echo>
<exec executable="make"/>
</target>
</project>
And the output I get so far is this one:
C:\Program Files (x86)\Jenkins\workspace\test>exit 0
[test] $ cmd.exe /C "ant.bat info && exit %%ERRORLEVEL%%"
Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre1.8.0_131\lib\tools.jar
Buildfile: C:\Program Files (x86)\Jenkins\workspace\test\build.xml
info:
[echo] Hello World - Welcome to Apache Ant!
[exec] rm -f test_*.s
[exec] arm-none-eabi-gcc.exe -O2 -Wall -S -c test.c -o test_gcc.s
[exec] make: arm-none-eabi-gcc.exe: Command not found
[exec] make: *** [Makefile:9: test_gcc.s] Error 127
[exec] Result: 2
BUILD SUCCESSFUL
Total time: 0 seconds
Finished: SUCCESS
Why do I get a BUILD SUCCESSFUL status while I got an Error?
N.B. I know I have to configure my PATH to include the toolchain. I would like to first understand this inconsistency.
By default, Ant's exec task does not fail the build when an error code is returned. However, this can simply be switched on with the failonerror attribute:
<exec executable="make" failonerror="true" />

Is it possible to run an executable from ant using a working directory other than the one which contains the executable? This small ant project demonstrates what I'm trying to achieve.
Folder structure
ant test
| build.xml
| bin
| | debug
| | | program.exe
| | release
| | | program.exe
| | inputs
| | | ...
| | outputs
| | | ...
build.xml
<project name="test" basedir="./">
<target name="run">
<exec executable="${configuration}\program.exe" dir="bin"/>
</target>
</project>
${configuration} is set to release.
bin needs to be the working directory so the executable can reference files in inputs and outputs correctly, so I want to be able to run the executable contained in bin/release from the bin directory. However, ant fails to find the executable:
BUILD FAILED
D:\ant test\build.xml:6: Execute failed: java.io.IOException: Cannot run program "release\program.exe" (in directory "D:\ant test\bin"): CreateProcess error=2, The system cannot find the file specified
I am able to work around this on windows by launching cmd.exe in the bin directory and then passing it the parameter release\program.exe, but I need to be able to use the ant file on multiple platforms, so I was hoping to find a consistent syntax.
One option I considered was using conditional tasks and having separate syntaxes for windows and unix. However, in the actual project, the exec statement occurs inside a macro, and the target calls the macro a large number of times. Since conditions can only affect things at the target level, I would have to duplicate the long list of macro calls for each syntax I wanted to target, e.g.
<target name="runAll" depends="runAll-win,runAll-unix"/>
<target name"runAll-win" if="win">
<myMacro-win .../>
<!-- Huge list of macro calls -->
...
<myMacro-win .../>
</target>
<target name"runAll-unix" if="unix">
<myMacro-unix .../>
<!-- Huge list of macro calls -->
...
<myMacro-unix .../>
</target>
The dir attribute specifies the working directory but the executable path is resolved against the project basedir. Hence the task will search for the executable D:\ant test\release\program.exe.
A simple solution is to add resolveexecutable="true" to the task call:
<target name="run">
<exec executable="${configuration}\program.exe" dir="bin" resolveexecutable="true" />
</target>
From the exec task documentation:
When this attribute is true, the name of the executable is resolved firstly against the project basedir and if that does not exist, against the execution directory if specified. On Unix systems, if you only want to allow execution of commands in the user's path, set this to false. since Ant 1.6
I have an application in a Jar and I wrap it in a exe with launch4j so is easy for the user to launch it (in windows). I have a certificate, so I sign the jar (I don't know if this is really necessary because it will be wrapped inside the exe) and I want to sign the exe but it corrupt the executable.
I use ant to make all the process and look like:
<signjar jar="${jar.location}" alias="${key.alias}" storetype="pkcs12" keystore="${key.file}" storepass="${key.password}" tsaurl="https://timestamp.geotrust.com/tsa" />
<launch4j configFile="launch4j_configuration.xml" fileversion="${version}.0" txtfileversion="${build}" productversion="${version}.0" txtproductversion="${build}" outfile="${exe.location}" jar="${jar.location}" />
<signexe file="${exe.location}" alias="${key.alias}" storetype="pkcs12" keystore="${key.file}" storepass="${key.password}" tsaurl="http://timestamp.verisign.com/scripts/timstamp.dll" />
I have found that is because when you sign the exe it broke the jar structure or something like this. But what I have also seen is that inside the launch4j folder is a sign4j folder that contains what I think is a program that solve this problem.
My problem now is how is used this program? And how can I integrate it in the ant script to sign the exe?
The README.txt file in the folder doesn't helped to me. Sorry if this so obvious but isn't clear for me. Also note that I'm using Ubuntu.
What I have found is that you must execute the sign4j command with the signing command as its argument. Something like:
sign4j jsign -s keyfile.p12 -a "(codesign_1091_es_sw_kpsc)" --storepass AVERYGOODPASSWORD --storetype pkcs12 -n MyProgram -u https://www.example.com MyProgram.exe
So, to integrate it into ant, you need to create an exec task. For example, something like:
<exec executable="sign4j">
<arg line="java -jar jsign-1.2.jar -s ${key.file} -a ${key.alias} --storepass ${key.password} --storetype pkcs12 ${exe.location}"/>
</exec>
It works also with other signing tools like for example authenticode from Microsoft, too ...
<exec executable="launch4j/sign4j/sign4j.exe">
<arg line="signtool.exe sign /fd SHA256 /f mycert.pfx /p foobar /t http://timestamp.verisign.com/scripts/timstamp.dll dist\myapp.exe"/>
</exec>
I use ant target as below to sign exe generated out of a jar file
<target name="signexe" depends="createExe" description="Signing Exe">
<exec executable="C:\Tools\Launch4j\sign4j\sign4j.exe">
<arg line="java -jar C:\3rdParty\jsign\jsign-3.1.jar
--keystore ${keystore.location} --alias ${key.alias} --storepass ${store.password}
--name 'Application Name'
--tsaurl http://timestamp.verisign.com/scripts/timstamp.dll
AppLauncher.exe"/>
</exec>
</target>
I am executing ant script in windows. In that consider that, i am executing dir command in exec task as below
<target name="dummy">
<exec executable="cmd" failonerror="true">
<arg line="/C DIRR"/>
</exec>
<exec executable="cmd" failonerror="true">
<arg line="/C cd /d c:\temp"/>
</exec>
</target>
Here I have given DIRR instead of DIR, this execution will fail. but the ant build is not failing. Its showing the error message as dirr is not recognised as internal or external command and the next command cd /d c:\temp also got executed. I want the ant script execution has to be stopped once error message comes.
I want to this script has to stop executing if error occurs in any one of the exec command. failonerror is also not helping. How to fail the ant build, if exec fails.
Note : I am using ant 1.8.2
Please note, that there are two levels of execution here:
Ant calls cmd.exe.
cmd.exe executes DIRSS.
You see, if the the second step fails, this does not necessarily mean, that cmd.exe does propagate the error back to Ant. This might be more obvious if the mentally replace the well-known cmd.exe with something "innocent" like foo.exe.
So the next step is to explore, why the second step behaves differently on your machine than on the machines of the commentators of your question. After that riddle is solved, you can get back to the Ant question.
A first step might be this: Open a new shell window and try
> cmd /c dir
> echo %ERRORLEVEL%
> cmd /c dir nonexisting-directory
> echo %ERRORLEVEL%
> cmd /c dirr
> echo %ERRORLEVEL%
Also tell us the version of your OS.
I'm trying to execute iisvdir from an ant script to clean and create a virtual directory before I compile my .net app in Visual Studio. I am running into a couple of strange errors one one build server, but another is running the script without any problem.
<exec dir="${SYSTEM32}" executable="cscript" failonerror="true">
<arg line='iisvdir.vbs /create "Default Web Site" ${RS_VIRTUAL_DIR} "${env.WORKSPACE}"'/>
</exec>
Results in:
[exec] Microsoft (R) Windows Script Host Version 5.6
[exec] Copyright (C) Microsoft Corporation 1996-2001. All rights reserved.
[exec]
[exec] Input Error: Can not find script file "c:\windows\system32\iisvdir.vbs".
And then
<exec dir="${SYSTEM32}" executable="cmd" failonerror="true">
<arg line='cscript iisvdir.vbs /create "Default Web Site" ${RS_VIRTUAL_DIR} "${env.WORKSPACE}"'/>
</exec>
Results in
[exec] 'reate' is not recognized as an internal or external command,
[exec] operable program or batch file.
Can someone help me figure out what might be wrong?
Is iisvdir.vbs where you say it is?
To get CMD.EXE to run a command, you need to use the /C switch.
For example:
cmd.exe echo Hello
...ignores the parameters and runs another interactive command prompt as a subshell.
cmd.exe /c echo Hello
...runs the "echo Hello" statement and returns immediately. Note: You can use /K if you want cmd.exe to continue running interactively after running the statement (not usually a good idea in a build script).
Your command:
cmd.exe cscript iisvdir.vbs /create etc.
...is getting parsed as if you'd really said:
cmd.exe /c reat etc.
This is because cmd.exe has (as with most MS command line tools) freaky command line parsing.
Update: Is this a 64-bit OS? If Ant is a 32-bit task, then it'll actually (silently) be looking in C:\Windows\SysWOW64 for cscript.exe and iisvdir.vbs. Are they there? If not, you should use C:\Windows\SysNative. In a 32-bit task, this is aliased to the real C:\Windows\System32 directory.
I don't know if it's the cause of your problems but I notice that you are using a single quote (') for <arg line='. All the examples I've seen use a double quote (") I know you are enclosing items with spaces in double quotes so it may be necessary to escape them out? Perhaps moving the code into a batch file which you can test before running via Ant?
Not sure if this will help but could point you in the right direction.
The Ant exec task has an output property which can be used to tell Ant where the output goes. I've used it to redirect the output to a file. The thing is, if I don't do something with the output, the stuff that Ant prints isn't that much of a help - it's not complete.
Is there someway of setting the output property to System.out?
When executing a batch file with ant's apply or exec tasks on Windows, I found there are special cases where some of the stdout and stderr is not captured by ant. (For example: if you call a batch file that in turn calls other commands (like node.exe), then the stdout and stderror from the child node.exe process is lost.)
I spent a long time trying to debug this! It seems that the batch file's stdout and stderr is captured, however commands called by the batch file are somehow not seen by ant. (perhaps because they are separate child processes). Using the output and error attributes as suggested above doesn't help because only some of the stdout and/or stderr is captured.
The solution I came up with (a hack) is to add these arguments at the end of the command:
<!--Next arg: forces node's stderror and stdout to a temporary file-->
<arg line=" > _tempfile.out 2<&1"/>
<!--Next arg: If command exits with an error, then output the temporary file to stdout, -->
<!--delete the temporary file and finally exit with error level 1 so that -->
<!--the apply task can catch the error if #failonerror="true" -->
<arg line=" || (type _tempfile.out & del _tempfile.out & exit /b 1)"/>
<!--Next arg: Otherwise, just type the temporary file and delete it-->
<arg line=" & type _tempfile.out & del _tempfile.out &"/>
Because this hack only applies to windows, remember to add #osfamily="windows" to the apply or exec task. And create similar task(s) for `#osfamily="unix", etc but without these extra arguments.
The output of exec does go to standard out unless you specify the output attribute.
If you want to output to System.out, then simply do not specify the "output" attribute. If you would like to redirect to a file AND print it to System.out, you can use the tee command, which will redirect output to a given file and also echo it to standard out... I do not know if Windows supports "tee" or an equivalent.
Maybe you want to look at the error, logError, and errorproperty attributes of the exec task too. These deal with the handling of the standard error stream from the exec'd process. There may be useful information there that is going awol for some reason - which might account for the incompleteness you see.
But, if the exec'd process decides to close stdout or stderr and send them elsewhere - there's little you can do.
I have faced similar problem: the output of command execution was suppressed. Perhaps that is the side effect when running cmd under WinXP (I an using maven-antrun-plugin). Anyway setting output="con" worked out perfectly:
<configuration>
<target>
<exec executable="cmd" output="con">
<arg value="/c" />
<arg value="..." />
</exec>
</target>
</configuration>
Working with Ant and Gruntjs:
For anyone trying to get this to work using Gruntjs. I was able to get it working by doing the following (in combination with darcyparker's answer).
In my Ant Build File:
<target description="run grunt js tasks" name="grunt">
<exec dir="/path/to/grunt" executable="cmd" failonerror="true">
<arg value="/c"/>
<arg value="jshint.bat"/> // I broke each task into it's own exec
<arg line=" > jshint.log 2<&1"/>
<arg line=" || (type jshint.log & del jshint.log & exit /b 1)"/>
<arg line=" & type jshint.log & del jshint.log &"/>
</exec>
<exec dir="/path/to/grunt" executable="cmd" failonerror="true">
// another grunt task (IE: uglify, cssmin, ect..)
</exec>
</target>
jshint.bat
#echo off
pushd "C:\path\to\grunt\"
#ECHO _____________________________________________
#ECHO GRUNT JSHINT
#ECHO _____________________________________________
grunt jshint --stack >>jshint.log
NOTE: Path to grunt would be where your Gruntfile.js is located. Also note, I had to initially create the log file (to get it to work with darcyparker's answer) which would output the stack trace from that particular task. This would then give me the grunt task stack output from wherever I call my ant target.
Finally note that pushd "C:\path\to\grunt\" won't be necissary if your bat files are in the same directory as your Gruntfile.js.
I was experiencing this same kind of issue trying to get the build process to fail in Ant after Karma tests intentionally failed, and executing them with "grunt test".
Just added /c before "grunt test", and it worked like a charm
<target name="unittest">
<echo>*** KARMA UNIT TESTING ***</echo>
<exec dir="api_ui" executable="cmd" osfamily="windows" logError="yes" failonerror="true">
<arg value="/c grunt test"/>
</exec>
</target>
