The automatic download from cmake.org does not seem to work properly on Mac Slaves.

Jenkins spits the following error:

ERROR: Install from cmake.org [Auto Install]: No tool download known for OS `Mac OS X` and arch `x86_64`.

On the cmake.org website, the Mac OS X distributions are in fact using "Darwin" in their name and not "Mac OS X", so it is probably a very minor fix.

Thanks in advance.

gegles Thanks for reporting this.

Which JRE is installed on your system?
The plugin in fact compares the java system property os.arch against "amd64". IIRC, "amd64" is documented for the 64-bit JRE provided by Apple, but maybe OpenJDK uses a different value.

A related problem: cmake.org has both binaries for OS "Darwin" and "Darwin64" and uses "universal" and "x86_64" for the architecture value, which is confusing. Maybe you can explain what that mean.

With your knowledge of java on OS X, please inspect the mapping code at link https://github.com/jenkinsci/cmakebuilder-plugin/blob/master/src/main/java/hudson/plugins/cmake/CmakeInstaller.java#L373 and make suggestions, if you can understand java code.

I've just tested, the download part now works. Thank you!

Sadly, there is now another issue with the path for the cmake binary being different on Mac then on Linux.

For mac, the cmake CLI binary does not sit in the extracted "bin/" directory (like Unix), but in the "CMake.app/Contents/bin/" of the extracted cmake-3.3.2-Darwin-x86_64.tar.gz.

Here is the relevant part of the log:

JENKINS-30070 Fix path to cmake binary for Mac OS X

Please download and test the SNAPSHOT version at https://jenkins.ci.cloudbees.com/job/plugins/job/cmakebuilder-plugin/lastBuild/org.jenkins-ci.plugins$cmakebuilder/artifact/org.jenkins-ci.plugins/cmakebuilder/2.3.2-SNAPSHOT/cmakebuilder-2.3.2-SNAPSHOT.hpi

If it works, I will release it.

Thanks for your hard work.

I did have to do a bit of cleanup (delete previously downloaded versions), but once I had a clean slate, things are working great now. Thanks!

As far as I'm concerned, you can release it, but folks might encounter the same cleanup issue I had.

Cheers. G.

Thank you for testing it.
I was concerned, since the installation removes some dirs that come with the archive which might be needed on OS X.
