Takayoshi Fujiki created MNG-5686:
-------------------------------------
Summary: mvn cannot execute /usr/libexec/java_home/bin/java on OS
X.
Key: MNG-5686
URL: https://jira.codehaus.org/browse/MNG-5686
Project: Maven
Issue Type: Bug
Components: Command Line
Affects Versions: 3.2.3
Environment: Mac OS X 10.9.4
Reporter: Takayoshi Fujiki
Attachments: maven-bin-mvn.patch
>From 3.2.3, mvn cannot start and outputs the following error.
{code}
$ ./apache-maven-3.2.3/bin/mvn -version
Error: JAVA_HOME is not defined correctly.
We cannot execute /usr/libexec/java_home/bin/java

3.2.2 doesn't have this problem.
{code}
$ ./apache-maven-3.2.2/bin/mvn -version

When I modified {{bin/mvn}} like the following, this problem was gone.

Maybe MNG-5658 is related to this problem. {{/usr/libexec/java_home}} is a
command([java_home(1)|https://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man1/java_home.1.html]),
and {{$(command)}} is a style of [Command
Substitution|http://www.tldp.org/LDP/abs/html/commandsub.html] (Another(old)
style is {{`command`}}).
So removing "$()" breaks the JAVA_HOME detection on OS X.
