Question

I’m Running My Eclipse (Helios) in Ubuntu. I’ve added exec Maven Plug in. When i try to run Maven build I’m getting on IO Exception.

It’s try to execute Java in my Project Directory, so Getting on IO Exception.
I’ve Set up My JAVA_HOME, MAVEN_HOME, still it try to run Java from my project Directory.

I’ve added my pom file & the exception.

Answer 1

The executable command Can be a full path or a the name executable. In the latter case, the executable must be in the PATH for the execution to work.

The plugin will search for the executable in the following order:

relative to the root of the project
as toolchain executable
relative to the working directory (Windows only)
relative to the directories specified in the system property PATH (Windows Only)

i’ve tried with full path, it works.
