help needed with maven antrun plugin
Hi, I am facing a strange problem. I am able to successfully build using an ant build.xml but the same is failing when I am call it using antrun plugin. Has anyone faced similar issue and any clue on how this can be resolved? I don't want to use exec plugin as that will require ant to be installed on all developer machines. In my environment we are using maven 2.0.10, Java 1.6update5. For testing the ant compilation directly I used ant version 1.7.0. Thanks for your help. -Pankaj

RE: help needed with maven antrun plugin
Here's the exact error. [INFO] [ERROR] BUILD ERROR [INFO] [INFO] An Ant BuildException has occured: The following error occurred while executing this line: build.xml:118: com.bea.util.jam.internal.javadoc.JavadocClassloadingException: An error has occurred while invoking javadoc to inspect your source files. This may be due to the fact that $JAVA_HOME/lib/tools.jar does not seem to be in your system classloader. One common case in which this happens is when using the 'ant' tool, which uses a special context classloader to load classes from tools.jar. This situation elicits what is believed to a javadoc bug in the initial release of JDK 1.6. Javadoc attempts to use its own context classloader tools.jar but ignores one that may have already been set, which leads to some classes being loaded into two different classloaders. The telltale sign of this problem is a javadoc error message saying that 'languageVersion() must return LanguageVersion - you might see this message in your process' output. This will hopefully be fixed in a later release of JDK 1.6; if a new version of 1.6 has become available, you might be able to solve this by simply upgrading to the latest JDK. Alternatively, you can work around it by simply including $JAVA_HOME/lib/tools.jar in the java -classpath parameter. If you are running ant, you will need to modify the standard ant script to include tools.jar in the -classpath.

Re: help needed with maven antrun plugin
AFAIK maven munges up the java home in the system properties so that the
${java.home} is actually the jre inside the jdk and not the jdk... however
${env.JAVA_HOME} should still be the java home and the mvn scripts bomb out
if JAVA_HOME is not defined.

Here's my experience. I don't remember when I added this, but here is what
I use as a dependency for the maven-antrun-plugin:
sun.jdk
tools
1.6
system
${java.home}/../lib/tools.jar
Works for me, YMMV.
Hope that helps.
