Build Identifier: 20110615-0604 Installed the Eclipse 3.7 for Java developers (cocoa 64 bit), then the MTJ tools via "Install new..." -> all available sites -> type MTJ. I have this version installed now. Mobile Tools for Java 1.1.2.201106060709 org.eclipse.mtj.feature.group Eclipse.org I then manually added the hook into config.ini as described in the original MTJ install instructions. I have a working project from a 3.6 pulsar release. When trying to preprocess, I see the following error in the log. java.lang.NoSuchFieldError: ruleMemo at antenna.preprocessor.v3.parser.APPParser.<init>(APPParser.java:89) at antenna.preprocessor.v3.parser.Defines.addDefines(Defines.java:197) at antenna.preprocessor.v3.Preprocessor.addDefines(Preprocessor.java:325) at org.eclipse.mtj.internal.core.build.preprocessor.PreprocessorBuilder.preprocess(PreprocessorBuilder.java:692) at org.eclipse.mtj.internal.core.build.preprocessor.PreprocessorBuilder.doPreprocessing(PreprocessorBuilder.java:498) at org.eclipse.mtj.internal.core.build.preprocessor.PreprocessorBuilder.doBuild(PreprocessorBuilder.java:347) at org.eclipse.mtj.internal.core.build.MTJIncrementalProjectBuilder.build(MTJIncrementalProjectBuilder.java:70) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:728) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:199) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:239) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:292) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:295) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:351) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:374) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:143) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:241) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) I guess that the version of ANTLR that is picked up is not compatible with MTJ. Reproducible: Always Steps to Reproduce: 1. try and build an MTJ project with preprocessing enabled
I see that antenna.preprocessor bundle only provides a minimum version number for ANTLR runtime. Eclipse indigo ships both ANTLR runtime 3.2 and 3.0.1 and I think 3.2 is picked up. I will update the bundle and give a maximum supported version so that 3.2 is not used anymore.
A fix is released to git repository and you can pick up the update that includes the fix from http://download.eclipse.org/mtj/updates/nightly update site.
Hmm, now I get the following error Preprocessor invoked, but hook is not installed. Consult the installation instructions for MTJ. I do have the following in configurations/config.ini #This configuration file was written by: org.eclipse.equinox.internal.frameworkadmin.equinox.EquinoxFwConfigFileParser #Tue Oct 25 10:39:40 CEST 2011 org.eclipse.update.reconcile=false eclipse.p2.profile=epp.package.java osgi.instance.area.default=@user.home/Documents/workspace osgi.framework=file\:plugins/org.eclipse.osgi_3.7.1.R37x_v20110808-1106.jar equinox.use.ds=true eclipse.buildId=M20110909-1335 osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.200.v20110502-1955.jar@1\:start org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator/bundles.info eclipse.product=org.eclipse.platform.ide osgi.splashPath=platform\:/base/plugins/org.eclipse.platform osgi.framework.extensions=org.eclipse.mtj.core.hooks osgi.bundles.defaultStartLevel=4 eclipse.application=org.eclipse.ui.ide.workbench eclipse.p2.data.area=@config.dir/../p2/ I.e. the hook for osgi.framework.extensions=org.eclipse.mtj.core.hooks. But somehow that doesn't seem to be enough.
Reopening to take a look
Oh well guess nobody noticed this before, but this line of eclipse: https://github.com/eclipse/rt.equinox.framework/blob/e490d7954ccc2f68113309730a67bbdaa242055d/bundles/org.eclipse.equinox.launcher/src/org/eclipse/equinox/launcher/Main.java#L907 Seems to add a dot to the classpath of the "org.eclipse.mtj.core.hooks" library. entries[j] = one entry from the eclipse.properties: Content of eclipse.properties: http://git.eclipse.org/c/mtj/org.eclipse.mtj.git/tree/trunk/plugins/org.eclipse.mtj.core.hooks/eclipse.properties?id=2781779133edabd848add3a0b49b1ebacae4a1b0 I'm not really shure if this is intended but i guess it is not. But even if this would be correct it would probably get a problem with asm-all-3.0.jar, because the following line will fail: https://github.com/eclipse/rt.equinox.framework/blob/e490d7954ccc2f68113309730a67bbdaa242055d/bundles/org.eclipse.equinox.launcher/src/org/eclipse/equinox/launcher/Main.java#L980 So the classloader was looking for a file called "org.eclipse.mtj.core.hooks-*.jar.". So basically it doesn't even read the hookconfigurators.properties file after that. The only Solution for me was to add "Eclipse-BundleShape: dir" to the manifest of the plugin ,package it with maven again, and install it from the plugin-zip-file. That way it would take the classpath "org.eclipse.mtj.core.hooks-*/." instead, because the plugin gets stored inside a directory in the plugin-folder and not as jar file. I also modified the "Debug.java" because it throw Exceptions about not finding a Platform class. (But I'm not shure if this step is really needed, i changed this before i found the problem with the classloader) http://git.eclipse.org/c/mtj/org.eclipse.mtj.git/plain/trunk/plugins/org.eclipse.mtj.core.hooks/src/org/eclipse/mtj/internal/core/hooks/Debug.java?id=2781779133edabd848add3a0b49b1ebacae4a1b0 So i just used "DEBUG_GENERAL = false" for example.
