How to run IntelliJ and Maven on OS X?

I've got Maven to respond on IntelliJ (all env vars are set); but still -- the following error occurs:

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dclassworlds.conf=/usr/local/Cellar/maven/3.0.2/bin/m2.conf -Dmaven.home=/usr/local/Cellar/maven/3.0.2 -Dfile.encoding=MacRoman -classpath org.codehaus.classworlds.Launcher --no-plugin-registry --fail-fast --no-plugin-updates --strict-checksums --update-snapshots -f /Users/konzepz/Sites/wix/html/Express/pom.xml compile Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/classworlds/Launcher Caused by: java.lang.ClassNotFoundException: org.codehaus.classworlds.Launcher at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248)

Process finished with exit code 1

Any ideas?

Thanks!

I could get it to work only by setting IntelliJ IDEA -> Preference -> Maven -> Maven home Directory to "/usr/local/Cellar/maven2/2.2.1/libexec"

I followed the instructions (paraphrased below) from Vladimir Krivosheev in http://youtrack.jetbrains.net/issue/IDEA-21225 ... hope it helps

  • create a new .MacOSX folder in your home folder (if it doesn't already exist)

  • create a new environment.plist in the .MacOSX folder (with the following contents... change the path to match the folder that you installed maven into)

    {
"M2_HOME"="/usr/local/maven/apache-maven-3.0.0";
M2 = "/usr/local/maven/apache-maven-3.0.0/bin";

    }

logout of your account and then sign back in

EDIT - 20140827

FYI - Since answering this question, it appears that mavericks no longer supports the environment.plist method, see further details here...https://apple.stackexchange.com/a/125066/40942

I've had success in mavericks using the solution posted here https://superuser.com/a/390926/70256

...which involves opening the intellij preferences --> path variables and adding in the M2_HOME variable with the correct value for you environment.

In case you don't want to use the M2_HOME and want to direct the IntelliJ to the maven installation you can simply set it by:

  • goto File => Setting => Maven => Maven home directory
  • point to your maven build directory e.g. /usr/local/maven/apache-maven-3.0.4

A better way is to have a symlink e.g. 'latest' for the latest version and point your IntelliJ to use that for consistency, given latest points to the latest version of maven installed on your box.

Can you replace maven.home with MAVEN_HOME and see if the error persists?
