Mozilla rhino not compiling - ant

I am trying to compile commit 9c8bad6ec6d51a0abfb9f6e840e2dbec3e2fbcee of the Mozilla Rhino project to make some tests on it.
I cloned the repository to my server, and checked out the hash.
I then proceeded into compiling using ant, which returned errors on lines 128, 57 and 53 of build.xml.
I'm not 100% sure of what line 127 does:
<!--<antcall target="jar-src"/>-->
So I commented it out for the time being.
For lines 53 and 57:
<target name="compile-src" depends="prepare">
<ant dir="/home/dario/testEnv/181834/prefix/rhino"/> <- line 53
</target>
<target name="compile-toolsrc" depends="prepare">
<ant dir="/home/dario/testEnv/181834/prefix/rhino"/> <- line 57
</target>
They seemed to be setting the path for compiling the path. They did so dynamically originally, with some variable, but as that didn't work I changed it and wrote the actual path.
Not when I compile it doesn't throw any errors, but it does not generate the compiled classes.
Any ideas?

That version of Rhino is ancient.
You could fix your problem by using JDK version 1.4 to compile. The problem is that that version of Rhino contained code that was incompatible with the JDK 1.5 enhancements (specifically, it attempts to use enum as a variable name).
Alternatively, you could patch the build.xml to specify the source version to be 1.4 when compiling on the appropriate javac tasks.
More realistically, do you have any option of upgrading to a reasonably recent version of Rhino?

Ant: failed to create task or type runtarget

I am running into the following error when trying to run ant:
Problem: failed to create task or type runtarget
I am building on a mac 10.8.3.
Prior research has suggested that I add ant-contrib-0.3.jar to my ANT_HOME installation directory, which I have done (that had actually gotten rid of another 'failed to create task or type' error)
I used ant-contrib-0.3.jar because research suggested that this jar is mapped to the line:
< taskdef resource="net/sf/antcontrib/antcontrib.properties" />
which is in the build.xml file I am using.
The project builds on windows machines ( I even got it to build using https://code.google.com/p/winant/ ) but am trying to get it built on a mac. I am thus not looking to change the build.xml file.
An example of the run target line is:
<target name="setPASProps" depends="" description="setup the properties">
<property name="systemname" value="PAS"/>
<runtarget target="setSystemProps"/>
</target>
Here is some info from running ant -diagnostics

Thanks !
It would be helpful if you posted your build.xml too.
You usually get this error if Ant sees a task, but there's a problem with the definition.
Here's my recommendation:
In your project create a directory antlib/ant-contrib.
Download this zip file. Ant-contrib is a wee bit strange is that there is a separate jar for C compiling and for all of the other Ant tasks. The latest version is 1.0b3. When you unzip this zip file, you will see ant-contrib-1.0b3.jar inside this folder.
Put that ant-contrib-1.0b3.jar inside the antlib/ant-contrib folder.
Now, in your build.xml, use the following <taskdef/>:
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<fileset dir="${basedir}/antlib/ant-contrib"/>
</classpath>
</taskdef>
Make sure this is not inside a target. You want this to be executed before any targets are executed.
I like doing the definition this way because the Ant Contrib jar file becomes part of my project, and anyone who needs to run my project will not have to manually install the Ant Contrib jar before they can use my project.
Take a look at your build.xml and see where that <Runtarget> task is being used. I've never used it, and the documentation for this task is so clear and helpful. Actually, I'm not even sure if it works. If you are still having problems, you try to see if you can remove the defined <target/> that contains this task, and see if that gets rid of the issue.
Removed ant-contrib-0.3.jar and added ant-contrib-1.0b3.jar and ant-contrib.jar to my ANT_HOME directory since these are the jars installed with https://code.google.com/p/winant/ (and it was working on windows machines).
This did the trick.

bndwrap ant task not working

I'm trying to create an OSGi wrapper for the newest version of jTDS. I'm trying to add the wrapping process to the existing jTDS build process (Ant-based). I've downloaded the latest bnd.jar and added the following to the jTDS build.xml:
<taskdef resource="aQute/bnd/ant/taskdef.properties" classpath="bnd.jar"/>
<bndwrap trace="true" definitions="${basedir}/bnd" output="${build}/${ant.project.name}-${version}.osgi.jar">
<fileset dir="${build}" includes="*.jar"/>
</bndwrap>
I've also got a very simple bnd definition defined:
version=1.2.6
Export-Package: net.sourceforge.jtds*;version=${version}
Bundle-Version: ${version}
Bundle-Name: net.sourceforge.jtds
When I execute the dist task in Ant, it should be creating a JAR with the proper OSGi manifest. It IS creating another JAR, but the manifest is identical to the original.
If I execute the same wrap directly against the bnd JAR:
java -jar bnd.jar wrap -p bnd\jtds-1.2.6.bnd -o build\jtds-1.2.6.osgi.jar build\jtds-1.2.6.jar
I get the correct OSGi manifest.
What is going wrong during the Ant build?
It seems to be a problem with the latest version of bnd, found here. The Ant WrapTask was retooled some and just doesn't seem to work (maybe it's just misconfigured; documentation hasn't kept up with code).
I dropped in version 1.50.0 instead and everything worked as expected both through the bnd.jar and through Ant.

CruiseControl.net ndk-build on Windows 64bit without Cygwin

Latest Android NDK (version 8) allows to call ndk-build without additional cygwin installed.
My question is: can I plug this into CruiseControl.Net for periodical native build?
I assume that most likely I would need to use Ant as a build method and then add it to ccnet server config.
So the questions are:
How to call ndk-build.cmd from an Ant command
How to configure build.xml file?
I tried several approaches, but all of those failed. Could you give me some clues if it is possible at all?
I ran into the same problem (the CreateProcess failures, etc) when trying to invoke "ndk-build.cmd" directly from build.xml, using CC.net on Windows. I figured out how to get this to work, and so I felt compelled to share my solution.
First, create a 1-line Windows command file as follows (I named it "ndkwrapper.cmd"):
sh ndkwrap.sh %1 %2 %3
Next, create a simple bash shell script as follows (named "ndkwrap.sh"):
#!/usr/bin/sh
# Wrapper around ndk-build script for Windows
#
NDK_PROJECT_PATH=/cygdrive/c/workspace/agnc_android
export NDK_PROJECT_PATH
/cygdrive/c/Android/android-ndk-r8b/ndk-build $1 $2 $3
Of course, your exact paths (for your workspace and NDK directories) may be different, but note, in particular, that "/cygdrive/c" refers to "C:".
One very important step here, after you create the script above, is to convert the line endings from Windows to UNIX. You can do this with a utility called "dos2unix.exe" which is freely available. I don't remember where I got it, but it was part of some open source package of GNU/Linux tools ported to Windows. (Google on "UNIX file utilities for Windows".) If you don't convert the line endings, then sh or bash will have trouble reading the script, and you'll get all kinds of erros about "\r" ...
So, to invoke the equivalent of "ndk-build.cmd clean", for example, you'd type "ndkwrapper.cmd clean" to delete your intermediate and output NDK-related build files, in preparation for a full NDK build.
In your build.xml file for CC.net on Windows, you can invoke the NDK makefile as follows:
<tasks>
<exec>
<executable>cmd.exe</executable>
<baseDirectory>C:\Android</baseDirectory>
<buildArgs>/C ndkwrapper.cmd clean</buildArgs>
</exec>
Hope this helps!
Ben
i observed problems with running ndk-build as an CCNET task as well.
It took me a while, but at the end i noticed, that you have to provide HOST_OS and HOST_ARCH as ndk-build parameters to let it run.
<exec>
<executable>cmd</executable>
<buildArgs>/C ndk-build HOST_OS=windows HOST_ARCH=x86 -B NDK_PROJECT_PATH=[PROJECT] APP_BUILD_SCRIPT=[ANDROIDMKFILE] NDK_APPLICATION_MK=[APPLICATIONMKFILE] NDK_LOG=1</buildArgs>
<buildTimeoutSeconds>120</buildTimeoutSeconds>
</exec>
hope it helps anyone to save time.
Ok I got some progress, I am able to build the jni code via ant or nant but in both cases plugging it to the cc.net server config gives me strane error:
but now CC.net gives me strange errors:

</target>
</project>
As I said I can run a Nant.exe for my project and it cleans and build correctly.
It looks like the cc.net tries to run the other ndk-build commend which is used for linux and is missing some commands as uname.
Do you have any idea what cI could be doing wrong ?
The original question is asking about ant builds. This answer is related to a problem in CC.NET and ant and gradle builds are going to be affected in the same way.
We are using gradle and with some custom gradle tasks it is possible to compile the native code of your project as well by calling ndk-build.cmd (from a path that has no spaces in it).
After the gradle file is prepared properly shell initiated gradle builds will work but cc.net initiated builds will fail.
Our CC.NET task is defined as follows:
<exec executable=".\gradlew.bat">
<baseDirectory>$(projSrcDir)</baseDirectory>
<buildArgs>clean assemblePlayRelease assembleProRelease</buildArgs>
<buildTimeoutSeconds>900</buildTimeoutSeconds>
</exec>
The problem is related to a CC.NET bug that causes the shell variable names to be in lower case. Windows shell scripts do not care about the case of shell variable names but because the NDK fires up make variable case becomes an issue. The init.mk make file that is part of the build process relies on shell variable names to identify the host OS type. In particular the shell variable OS. Normally the OS value is defined like this:
OS=Windows_NT
But when the variable is passed to gradle from CC.NET it gets transformed into this:
os=Windows_NT
This causes the detection mechanism in init.mk to fail and tries to execute the unix detection sequence and looks for the Unix uname utility that is not present on Windows resulting in:
Android NDK: Unable to determine HOST_OS from uname -s:
Android NDK: Please define HOST_OS in your environment.
make.exe: Entering directory `D:/CC.NET/svncheckout/pes/src/project/src/main/jni'
make.exe: Leaving directory `D:/CC.NET/svncheckout/pes/src/project/src/main/jni'
And ultimately:
process_begin: CreateProcess(NULL, uname -s, ...) failed.
c:/ndk/build/core/init.mk:160: *** Android NDK: Aborting. . Stop.
FAILURE: Build failed with an exception.
The workaround is less then ideal but it gets the job done. The idea is to edit the ndk-build.cmd and change the case of the passed variables only when we are building from CC.NET.
Simply insert this code after the #echo off line in ndk-build.cmd:
IF DEFINED ccnetproject (
ECHO Applying Environment variable hack for CC.NET.
SET OS2=%os%
SET OS=
REM SET PATH=%path%
SET TEMP2=%temp%
SET TEMP=
)
IF DEFINED ccnetproject (
SET OS=%OS2%
SET OS2=
SET TEMP=%TEMP2%
SET TEMP2=
)
This script first makes temporary copies of values in the lower case OS and TEMP variables. Next it undefines them by clearing their values. An finally the reverse is done.
Two steps are needed because just saying
SET OS=%os%
doesn't do much since scripts are case insensitive. It first locates the OS variable, finds a lower case version and assigns its own value back to itself.
This was tested on CC.NET v1.6.7981.1, gradle v1.1.0 and Android NDK v10 (64bit).

Compile legacy Java code with java1.6 JDK

I'm compiling many legacy Java code probably written with Java1.3 and I got tons of errors like this:
Copydir.java:128: warning: as of release 5, 'enum' is a keyword, and may not be used as an identifier
[javac] (use -source 5 or higher to use 'enum' as a keyword)
[javac] Enumeration enum = filecopyList.keys();
It's too time consuming to replace each instance of enum with _enum so I added source="1.3" in ant javac task as below (based on examples from http://ant.apache.org/manual/Tasks/javac.html). But I still got the same compile error. I've tried to change source = 1.4,1.5, and still same error.
<javac srcdir="${src.dir}"
destdir="${build.classes}"
debug="true" debuglevel="lines,vars,source"
source="1.3"
deprecation="off"
optimize="on">
What is the right way to tell comiler that the source is written in 1.3, but I want to compile it to run in 1.6? I'm using jdk1.6.0.26 and ant 1.8.2
That's a warning, not an error. Unless there are other errors in the build that should work just fine.

checking latest version in version control

i am currently writing an ANT script which will include some intelligence to check for things. I am using SnapshotCM from True Blue Software as my version control and using CruiseControl as a framework for my nightly build.
Basically, I will need to always check for the latest version found in my version control and execute commands. In this case here is an example:
<project name="nightly_build" default="main" basedir="checkout">
<target name="init">
<property file="initial.properties"/>
</target>
<target name="main" depends="init">
<!-- need some code to set variable -->
<!-- need some code to increment variable -->
<!-- need some code here to check for the latest version -->
<exec executable="C:/Program Files/True Blue Software/SnapshotCM/wco.exe">
<arg line='-f -R "C:/Work/7.10.000_Tip/7.10.000_Tip_GUI_TEST/"'/>
</exec>
</target>
</project>
In the code above, I will load the "initial.properties" file.
The algorithm should be as follow:
load the initial properties file
get the build_number
increment build_number by 1 (let this new variable be X)
if X is found, increament X by 1 (if not found jump to 6.)
if X is found, repeat 4 (until X cannot be found)
else use the build number inside the <arg line ='-f -R "C:/..../7.10.100.X..../"'/>
The initial.properties file is as follow:
Major_Version=7
Minor_Version=10
Project_Number=100
Build_Number=036
Product_Version=${Major_Version}.${Minor_Version}.${Project_Number}.${Build_Number}
can anyone guide me on that?
Ant is not a programming language. It's a dependency matrix language.
That means you don't specify execution order in Ant. Ant will calculate the order it needs to run the targets. It also means Ant doesn't have the ability to do loops, or even change the value of a property once it is set.
There are a few packages that build upon Ant. The old standby is the Antcontrib. Antcontrib has the concept of variables which are like mutable properties. It also has various looping structures. However, I'm not sure if the <foreach> or <for> tasks will do what you want...
Searching sequentially for the next build number is something you can do in a shell script. In fact, I highly recommend this.
I use Ant for builds only and keep my CM functions outside of my build.xml file. Instead, I rely on my build system to do everything that's not related to the build itself. This includes checking out the code, saving the artifacts, and compiling unit tests. This way, if I change the way I use my continuous build system or my version control system, I don't have to modify my build.xml files.
