Config Maven 2 to print out javac commands during compile phase
Question
Is there any way to force Maven 2 (>2.0.10) to print the actual javac commands it's executing. We keep running out of memory even though we've bumped up the max using MAVEN_OPTS. I'd like to be able to see the actual command being executed that is running out of memory.
I've tried using the verbose setting below in the pom file's plugin management section but that doesn't seem to give me the javac command:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
<maxmem>1024m</maxmem>
<compilerArguments>
<verbose/>
</compilerArguments>
</configuration>
</plugin>
Solution
Have you tried running Maven with the -X
command to print debugging information?
$ mvn -?
...
-X,--debug Produce execution debug output
The maven-javac-plugin should then print out the classpath being used, the source directories/path, etc.
