homebrew ant

[michahell]

Hi,

Not sure if this has been reported before (could not find any issue on GH, open or closed) but after a brew install ant the following command does not work for me:
$ ant -version
gives
Error: Could not find or load main class org.apache.tools.ant.launch.Launcher
And also executing ant --execdebug fails with
``exec "/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/jre/bin/java" -classpath "/usr/local/Cellar/ant/1.9.4/lib/ant-launcher.jar" -Dant.home="/usr/local/Cellar/ant/1.9.4" -Dant.library.dir="/usr/local/Cellar/ant/1.9.4/lib" org.apache.tools.ant.launch.Launcher -cp ""
Error: Could not find or load main class org.apache.tools.ant.launch.Launcher`

What could be the cause of this? In the meanwhile, will try using ant outside homebrew.

Did you forget about #32851?

Do you have ANT_HOME set?

Aha, yes that was the issue thread I was looking for but could not find.
So I have set ANT_HOME as follows:

export ANT_HOME=/usr/local/Cellar/ant/1.9.4/libexec/
export PATH=$PATH:/usr/local/bin/ant

and now ant -version and ant --execdebug run without errors. Not sure why I could not find these instructions explicitly in the previous thread, it's quite buried in one of the comments.

But thanks for the pointer the the earlier thread!
