Hi Sahoo,

Maven has two distinct phases when producing artifacts: the build
phase and the install phase. From your description, the jar was built
ok but not installed. If you run mvn jar:install in the project that
builds the jar, does it get copied to your local repo?

Maven goals that are single words are locally defined. It sounds like
the "install" goal doesn't actually jar:install the artifact. Look at
your project for the definition of install.
