Hi,
I have trouble to execute my ant script programmatically using code. Everytime I try to run the code, I would get an error saying:
BUILD FAILED
X:\eclipseMT\runtime-workspace\testTest\diagram1_Sc2_TestScript.xml:68: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jdk1.6.0_12\jre"
I have tried various way to solve this problem including checking my classpath, JAVA_HOME, project Build_Path, include external jar (tools.jar) and so on but it still doesn't work. Just some notes, I can run the script if I'm running it using ant in command line and Eclipse Ant executor function. This indicate that the ant script is working as intended.
Can anyone give an idea how to solve this?
The code is in a basic normal Java project structure.
This is the code that execute the ant script
Project p = new Project();
try {
p.setUserProperty("ant.file", buildFile.getAbsolutePath());
DefaultLogger consoleLogger = new DefaultLogger();
consoleLogger.setErrorPrintStream(System.err);
consoleLogger.setOutputPrintStream(System.out);
consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
p.addBuildListener(consoleLogger);
p.fireBuildStarted();
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());
p.fireBuildFinished(null);
} catch (Throwable t) {
t.printStackTrace();
p.fireBuildFinished(t);
return false;
}
and this is my ant script:
