I finally found the fix to this. From the top...
Downloaded/installed Maven's latest version...
Downloaded j2objc-0.9.1...
set the path for Maven...
export M2_HOME=/Users/Craig/apache-maven-3.2.1
export PATH=$PATH:$M2_HOME/bin
ran 'make dist'...it still gave me the error above
i then changed this path...
export M2_HOME=~/.m2
ran 'make'
WORKED!
Maven was looking at the wrong location for "../repository/com/google/findbugs/jsr305/2.0.2/jsr305-2.0.2.jar".
Changing the path before you run 'make' fixes this issue.
Once the make command finishes, run:
export PATH=$PATH:/<j2objc location>/dist
This allows you to use the commands j2objc and j2objcc.
