Packaging fails if Mesos is built with --disable-java

[frankscholten]

I configured and built Mesos by running ../configure --disable-java and when I run

$ build_mesos --src-dir ~/src/mesos --build-dir ~/src/mesos/build --prebuilt --configure-flags '--disable-java --disable-python --enable-libevent --enable-ssl'

it fails because it cannot find the mesos jars.

mv: cannot stat '/home/frank/src/mesos/build/src/mesos-*.jar': No such file or directory
Makefile:12: recipe for target 'debian' failed
make: *** [debian] Error 1

The problem is with the jars function in build_mesos

function jars {
  mkdir -p usr/share/java/
  if [[ -d "$build_dir"/src/java/target ]]
  then mv "$build_dir"/src/java/target/mesos-*.jar usr/share/java # Mesos >= 0.18.1
  else mv "$build_dir"/src/mesos-*.jar usr/share/java             # Mesos <  0.18.1
  fi
}
