Build break?

I get the following error when I am trying to build bazel from the latest code.

$ ./compile.sh

It means that it does not found the jar command. I will fix that today.

[damienmg]

reproduced: remove jar from PATH and clean compile.sh

[huahang]

Just curious, I think the jar command is in my PATH?

$ which jar
/data/users/huahang/opt/jdk/linux-x64/jdk1.8/bin/jar

[damienmg]

Huh but it is probably not in the path that Bazel is using.

Do you have jar in /usr/bin or /usr/local/bin?

[huahang]

No, I don't. And it builds if I copy a jar binary in /usr/bin. Yet still, I think I would be nicer if the jar command could be loaded from $JAVA_HOME.

Thank you! :-)

[damienmg]

The fix to use the jar from JAVA_HOME is in our internal source repository and should be in a few hours :)

@damienmg why you only add "/usr/bin or /usr/local/bin" to "$PATH" when running compile.sh ???

I think you should use system's PATH variable .

or how cound I modify the PATH variable ???

@lisendong This issue is closed, do you mind creating a new issue with the details of your problem?

when I install bazel-0.9.0-dist by compile.sh, I met:

ERROR: /tmp/bazel_Bcmpd1a6/out/external/googleapis/BUILD.bazel:127:1: error executing shell command: 'cp 'bazel-out/k8-opt/bin/external/googleapis/google_watch_v1_java_grpc_srcs.jar' 'bazel-out/k8-opt/bin/external/googleapis/google_watch_v1_java_grpc_srcs.srcjar'' failed (Exit 127): bash failed: error executing command

/bin/bash: cp: command not found
Target //src:bazel failed to build

I have tried
--action_env=PATH
but it doesn't work.

"exec env - /bash/bash -c" is a really strange design. I don't want to discuss the reason of the design. But I think you should give a easy way, we could modify only several script to propagate $PATH env var
