I've found the problem. Plexus (which runs the compiler and commandline) is
quoting each argument. So for this configuration:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<target>1.6</target>
<source>1.6</source>
<compilerArguments>
<verbose />
<bootclasspath>${java.home}/lib/rt.jar</bootclasspath>
</compilerArguments>
<compilerArgument>-implicit:none -proc:none</compilerArgument>
<fork>true</fork>
</configuration>
</plugin>
</plugins>
</build>
mvn clean compile -X gives the following output:
[DEBUG] Command line options:
[DEBUG] -d /home/nick/workspace/buildserver-test-project/trunk/target/classes
-classpath /home/nick/workspace/buildserver-test-project/trunk/target/classes:
/home/nick/workspace/buildserver-test-project/trunk/src/main/java/nl/iprofs/sandbox/buildservertest/App.java
-g -nowarn -target 1.6 -source 1.6 -bootclasspath
/usr/lib/jvm/java-6-sun-1.6.0.00/jre/lib/rt.jar -verbose -implicit:none
-proc:none
[INFO] Compiling 1 source file to
/home/nick/workspace/buildserver-test-project/trunk/target/classes
While it is actually executing:
/usr/lib/jvm/java-6-sun-1.6.0.00/bin/javac -d
/home/nick/workspace/buildserver-test-project/trunk/target/classes -classpath
/home/nick/workspace/buildserver-test-project/trunk/target/classes:
/home/nick/workspace/buildserver-test-project/trunk/src/main/java/nl/iprofs/sandbox/buildservertest/App.java
-g -nowarn -target 1.6 -source 1.6 -bootclasspath
/usr/lib/jvm/java-6-sun-1.6.0.00/jre/lib/rt.jar -verbose "-implicit:none
-proc:none"
(Much more quotes, but just for the idea) If I execute this myself, javac
indeed gives the error as described.
I guess, this should be a feature request for the maven-compiler-plugin, to
indeed accept multiple compilerArgument options. Maybe something like this:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<target>1.6</target>
<source>1.6</source>
<compilerArguments>
<verbose />
<bootclasspath>${java.home}/lib/rt.jar</bootclasspath>
<compilerArgument>-implicit:none</compilerArgument>
<compilerArgument>-prox:none</compilerArgument>
</compilerArguments>
<fork>true</fork>
</configuration>
</plugin>
</plugins>
</build>
Hth,

Subject: RE: Not able to pass multiple arguments to javac
The fault message you see is actually from javac itself. You're trying to add
options that are not supported by javac. All javac options are "supported" by
the mojo, it simply passes them to javac.
Why would you want to add options to javac which are not supported by javac?
With regards,
Nick Stolwijk

Yes, I knew that approach, but the options I actually want to pass are
not supported by the mojo. nowarn and verbose were just used as
examples; I want to pass -proc:none and -implicit. They are not
supported by javac. There are many such options which are not supported
by the mojo. I thought compilerArgument is the way to use them. But, it
is *not* working.
Thanks,
