If I have small Blackberry project with just 10 or less java class files, and if I try to build it with ANT, then it works fine. But my actual Blackberry Project has more than 600 java classes in various packages. I get following Error while trying ANT.
“I/O Error: Cannot run program “java.exe”: CreateProcess error=87”
I assume you are using bb-ant-tools. The docs for the generatesourcelist attribute to the rapc ant task say
Generate list of source files in text file. Set this to true when java returns "CreateProcess error=87" on Windows. Optional, defaults to false.

When doing an ant build (thought jenkins) for a test project, I get the below error. As this test project will be deployed in tomcat why does the build require a netbeans specific module
Obviously I can add the jar file to a path in jenkins and then continue the build, but want to know why it needs a netbeans specific jar?
Is it because the project setup in Netbeans is wrong?
Thanks in advance.

======Error below here =========
var/lib/jenkins/workspace/DeployTest2/nbproject/build-impl.xml:797: The libs.CopyLibs.classpath property is not set up.
This property must point to
org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part
of NetBeans IDE installation and is usually located at
/java/ant/extra folder.
Either open the project in the IDE and make sure CopyLibs library
exists or setup the property manually. For example like this:
ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar
I'm relatively new to using build files and Ant to compile and execute from a command line so i wanted to know how it would be possible to modify the build-impl.xml file auto generated from netbeans so that after it compiles it also executes the program.
Currently when i type just "ant" in the command window where the build.xml file is listed it compiles and etc but then says
-do-jar-copylibs:
[copylibs] Nothing to copy.
[echo] To run this application from the command line without Ant, try:
[echo] java -jar "C:\Users\Eric\Documents\Word Documents\Java Test Code\NetbeansVersion\Cops\dist\Cops.jar"
I can run that command and it will run fine, but i want the program to execute by just typing ant.
The build.xml file - Pastebin
Build-impl.xml file - Pastebin
There are a couple "tasks" available in ant that you could use to accomplish this.
You can use either of these:
Java Task,
Exec Task
Those documentation pages provide examples as well. Before you go there though, you might want to start at the basic manual to get an idea of the structure of an ant build file to determine where and how you want to add this execution step in.
It feels a little "off" to me to have your build script executing the program, but I'm sure you've got a reason, so I might suggest adding a new target that does the build steps and then also runs this command to kick off the program. That way you've still got the option of running the build without running the program.
trying to make a multi module project I dowloaded the samples in github: I use this folder
https://github.com/SonarSource/sonar-examples/tree/master/projects/multi-module/sonar-runner/java-sonar-runner-modules-own-configuration-file as a project base dir
In a command line in this folder, I type /opt/sonar-runner/bin/sonnar-runner
First thing I find is that sonar-project.properties has a property named sonar.sources=src, but executing throws
Exception in thread "main" org.sonar.runner.RunnerException: You must define mandatory properties: sources
Then I correct this property with sources=src and runner execution finish, adds the project to my sonar server, but no code, modules or file is detected. It is like if all project is empty.
It is exactly the same with other examples and with my own project. No matter if is java, python...
Any help is welcome
You are using an old version of Sonar Runner and/or Sonar. Please update to the latest versions (Sonar Runner 2.2 and Sonar 3.5.1).
My ant files are already present and I am not allowed to change those for various reasons. I have created a batch file and I am writing all those ant commands in that batch file just to automate the process. The code looks something like this
1. cd abc
2. ant realclean && ant
3. cd..
4. cd pqr
5. ant realclean && ant
6. cd..
However now I have to check if the build fired on line 2 is successful then only goto line 3 otherwise exit.
I googled a bit and found %errorlevel% as one option but it is not working in my case.
Any suggestions?
Thanks in advance.
How about adding another ANT file which contains the tasks to execute the existing ANT files?
That would give you error handling without doing anything, you could reuse that file on different OSs and your CI server and the syntax would be saner than batch...
You can have ANT execute, say project.xml, with ant -f project.xml
[EDIT] You don't even have to change the existing projects: Just create a new project, assign paths to the old projects to properties in the new build.xml and then you can build the old projects from the new one.
This gives you:
A sane[*] syntax that you already know (no need to learn the ugly/buggy/handicapped rules of DOS batch programming; you did know that DOS was once named QDOS "Quick and Dirty OS", yes?)
Proper error handling
A simple way to pass arguments to the sub-builds
Cross-platform support
Useful error messages when something goes wrong
[*]: Compared to DOS...
I'm having problems building my project, using an Ant script, from the command prompt using Ant itself. It can't find a certain import for a particular Java file in my project (which has nearly 5,000 source files as it is). The import is included in a .jar package whose location I have set in the Ant file itself. (As a pathelement, along with other needed JARs that either are fine, or haven't tried to been used when the crash occurs). The crash happens with javac, with the simple message of "import etc.ect.* cannot be found at line etc" Oddly enough, I can build the project just fine from the Ant file using an IDE like Eclipse. Any ideas what could be wrong? Thanks!
Wow, the solution was completely unrelated. It was a dumb fault in the java code where the class was trying to import .* from a directory that only had folders in it. For some reason, Eclipse didn't seem to mind, but javac did!
Eclipse's root classloader contains a lot of classes, when you run ant from console there's much less.
Just tell javac task to use the required .jar, and you'll be fine.
You should post the stack trace, does it say "import required by ..."? ( I forget the exact text). Likely there's a jar that's available in your eclipse environment that is not included in your ant script. Look in the stack trace for the missing class to identify the jar that's not being included in your build.
