Trouble with building using Bazel #54

Closed ciera closed 9 years ago

ciera commented 9 years ago

I got the following email from Yu Lin.

I can't build shipshape anymore (my plugin works fine before this upgrade), it gives the following error:

It says "jar: command not found", but jar can be executed actually. Do you know why?

What version of Bazel is Yu Lin using?

yulin2 commented 9 years ago

I cloned it from github bazel's master branch. I found if I cp 'jar' into /usr/bin, I can compile.

collinw commented 9 years ago

Is jar not on your PATH by default?

yulin2 commented 9 years ago

It is on my path and I can execute it. But bazel still reports "jar: command not found". However, after I did "ln -s real/path/to/jar /usr/bin/jar", I can compile. I think it might be a issue of bazel. See here: https://github.com/google/bazel/issues/245

What is your JAVA_HOME? I just ran into my own problems using Bazel with a not-quite-right JAVA_HOME value: https://github.com/google/bazel/issues/268

yulin2 commented 9 years ago

My original JAVA_HOME was /usr/lib/jvm/java-7-openjdk-amd64. But I renamed java-7-openjdk-amd64 to openjdk-7 and set JAVA_HOME to /usr/lib/jvm/openjdk-7 (because I couldn't build the master branch of bazel when using name java-7-openjdk-amd64). Probably this action broke the symlink usr/bin/jar -> /etc/alternatives/jar -> /usr/lib/jvm/java-7-openjdk-amd64/bin/jar, thus raised the above error.

Now that I checkout bazel version 43b2ea7, I can build it using JAVA_HOME /usr/lib/jvm/java-7-openjdk-amd64. I restored the symlinks, and now I can build shipshape.
