On ubuntu 11.10, with maven2, here’s the error code:

Unable to locate the Javac Compiler in:

/usr/lib/jvm/java-6-sun-1.6.0.26/../lib/tools.jar

Not sure why it’s adding the “..” in the path?

My tools.jar is at /usr/lib/jvm/java-6-sun-1.6.0.26/lib/tools.jar

I have done:
sudo apt-get install sun-java6*
sudo update-alternatives –config java , and chosen sun-java-6

uncommented the deb-src /etc/apt/sources.list

/home/raymond/.bashrc

JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.26
export JAVA_HOME

~/.profile

JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.26
export JAVA_HOME

/usr/lib/mvn

exec "$JAVACMD" \
  $MAVEN_OPTS \
  -classpath "${M2_HOME}"/boot/classworlds.jar \
  "-Dclassworlds.conf=${M2_HOME}/bin/m2.conf" \
  "-Dmaven.home=${M2_HOME}"  \
  "-Djava.home=${JAVA_HOME}" \
  ${CLASSWORLDS_LAUNCHER} $QUOTED_ARGS

pom.xml, I have this in my builds, plugins

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>

                <target>1.6</target>
            </configuration>
        </plugin>

    It seems I needed to remove this line: “-Djava.home=${JAVA_HOME}” \ from /usr/lib/mvn that I posted in the question. I had added that line following a suggestion from googling. I guess setting the extra java_home had some conflicts.

    I think for ubuntu, it’s easier to just install all sun-java6 packages. I only installed -jdk earlier and ran into all sorts of problems trying to get mvn install to work. I think it started to work since I installed everything, I just had a bogus fix in there that prevented it from installing.
