OSX Yosemite Ant

[michahell]

Hi,

I am currently running OSX Yosemite beta 4, and this is what my ant installation adventure looks like:
which ant
returns nothing
ant
-bash: ant: command not found
brew install ant
/usr/local/Cellar/ant/1.9.4: 1597 files, 39M, built in 17 seconds
which ant
/usr/local/bin/ant [ o.k., great! ]
ant --execdebug
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 [ uhh wut ? ]
cd /usr/local/Cellar/ant/1.9.4/ *TAB*
INSTALL_RECEIPT.json
bin/
libexec/

[ so, no /lib folder ]

But, there is a /lib folder in /libexec:
cd /usr/local/Cellar/ant/1.9.4/libexec/lib/

Is this something OSX Yosemite specific? or am i doing something wrong? I never had similar problems when i was on OSX Mavericks :(

[update]

if i execute the following:

"/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/jre/bin/java" -classpath "/usr/local/Cellar/ant/1.9.4/libexec/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 ""

then the output becomes:

Buildfile: build.xml does not exist!
Build failed

Which makes sense, because in my root (~/) i don't have any buildfiles. Halp ?

[michahell]

Hmm, i have installed Ant the good old way and it seems to me that the brew formula for ant is missing the lib directory or at least the folder structure is different to this structure:
http://ant.apache.org/manual/index.html

[jacknagel]

It's installed the way it is (in libexec) because we don't want all of the jar files present linked into /usr/local/lib.

[michahell]

I don't understand... ant simply does not work then, at least in my case. How can you get it to work then? And could you maybe explain to me why they would be automatically linked into /usr/local/lib ? Does homebrew automagically do this with /lib folders?

[jacknagel]

I'm not denying there is a problem (thought it does work for at least some use cases; several things in homebrew depend on it at build-time).

And could you maybe explain to me why they would be automatically linked into /usr/local/lib ? Does homebrew automagically do this with /lib folders?

Yes. In /usr/local/Cellar/<name>/<version>, files in lib will be linked into the top-level lib. The same goes for bin, sbin, and others.

[michahell]

Aha, thank you. I can understand that we don't want that. Oh well, i'm fine with going for the 'regular' .pkg installation for ant (i'm using it together with IntelliJ TeamCity, which AFAIK just needs to be able to run ant in your project folder), although it's an addiction to have as many stuff installed by homebrew and homebrew-cask, of course 👍

[jacknagel]

If it doesn't work, there's a bug.

[michahell]

oops, too quick!

[jacknagel]

On 10.9, I see this:

$ ant --execdebug
exec "/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/jre/bin/java" -classpath "/usr/local/Cellar/ant/1.9.4/libexec/lib/ant-launcher.jar" -Dant.home="/usr/local/Cellar/ant/1.9.4/libexec" -Dant.library.dir="/usr/local/Cellar/ant/1.9.4/libexec/lib" org.apache.tools.ant.launch.Launcher -cp ""
Buildfile: build.xml does not exist!
Build failed

so it seems to be dereferencing the symlink correctly and looking in libexec/lib.

Can you gist your brew --config and brew doctor?

[jacknagel]

For me it also works on 10.10:

$ uname -a
Darwin vm-mavericks.local 14.0.0 Darwin Kernel Version 14.0.0: Tue Sep 23 23:01:41 PDT 2014; root:xnu-2782.1.97~6/RELEASE_X86_64 x86_64
$ ant --execdebug
exec "/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home/jre/bin/java" -classpath "/usr/local/Cellar/ant/1.9.4/libexec/lib/ant-launcher.jar" -Dant.home="/usr/local/Cellar/ant/1.9.4/libexec" -Dant.library.dir="/usr/local/Cellar/ant/1.9.4/libexec/lib" org.apache.tools.ant.launch.Launcher -cp ""
Buildfile: build.xml does not exist!
Build failed

[michahell]

Ha, that's weird. It must have something to do with my environment then:
brew --config: https://gist.github.com/michahell/c3ae790caaf3da6f7c18
brew doctor: https://gist.github.com/michahell/93bef1ebd3c504ad2ec9
This is without ant being installed through homebrew at the moment though.

[michahell]

I do run doctor quite regularly but i still needed to clean up some mess created by some scientific robot simulator package i downloaded and tried to compile, sorry for that :)

[DomT4]

What's the status on this? I presume if this is tagged user config it doesn't need adding to the 10.10 fail list?

[jacknagel]

Correct, it does not appear to be a 10.10 issue.

[jacknagel]

I can reproduce this if I set ANT_HOME to /usr/local/Cellar/ant/1.9.4.

That may not be the exact problem here, but I think it is safe to assume this is an environment issue rather than a problem with the formula.

[khawkins]

So we shouldn't be setting ANT_HOME to homebrew's ant install location? Is the setting of ANT_HOME itself a legacy practice, or is there some other rationale for the setting not to work?

[jacobg]

I just ran into this problem. Solution was to just download Ant directly from Apache and copy is to /usr/local

[cloudbring]

I was having the same issue. I had set my $ANT_HOME according to a guide for Appium testing. Once I unset ANT_HOME it worked without issue. $ANT_HOME as others have said is an outmoded setting.
