Eclipse comes with its own compiler, so it only needs the JRE to run. The command line needs the JDK, which you don't have installed. Install the JDK, set $JAVA_HOME, and make sure $JAVA_HOME/bin is on your path. See the bottom of the following page for detailed instructions: http://maven.apache.org/download.cgi If you're uncomfortable about using a different Java version between command line and Eclipse, you can always point Eclipse to the JRE inside the JDK and use that as the default JRE for Eclipse and the IDE. . . . just my two cents /mde/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJUpC/HAAoJEEFGbsYNeTwtO2kIAKEr2DC7OZt2hNMDhpuXtPqF /XtQHTMRR6W0SFXXkCDe4tqa2mGpQLSNUjXYUoDyw9QqX0YiS/X4kZwsPZOSjvrV fyYccm48U1/njdS6yiWbeuDqVSHGvWfrf7vv1L+/j28YhI8ZxM9PaXXJ05iBECmW t88hDHHNJpewf9IkIED5EHyFhie+pLqh+nITtLdrKx70zUwr6nVVXDglfbUbAuMK LueQ8hGWeQdpaj98zo0BnJYpi2bIRQ7inLNOthRDgSBZkcRVWHln4Gv05UFt/vhP en924SAlSRrSenKub7HhWzI0GaGnSGSyf1TRY75za6zgSNWbGVieb36pFyoqYd4= =BFis -----END PGP SIGNATURE----- --- This email is free from viruses and malware because avast!
