SonarQube Local Script in IntelliJ can't find mvn (IOException/No such directory)

Question

My maven build works fine in IntelliJ IDEA. That is not the issue. The issue is relating to SonarQube Community Plugin.

ERROR 17:08:38.358 > java.io.IOException: Cannot run program "mvn" (in directory "/Users/chrismanning/Projects/Registry/registry/idea-files"): error=2, No such file or directory

Local analysis script:

mvn sonar:sonar 
-DskipTests=true 
-Dsonar.analysis.mode=issues
-Dsonar.scm.enabled=false 
-Dsonar.scm-stats.enabled=false 
-Dissueassignplugin.enabled=false 
-Dsonar.preview.excludePlugins=emailnotifications,issueassign 
-Dsonar.report.export.path=sonar-report.json

I definitely have maven installed and in my path. (it's symlinked in /usr/local/bin)

If you're using Yosemite (like I am) you must set environmental variables this way

1. Create new file at ~/Library/LaunchAgents/environment.plist

2. Add this code block and modify to appropriately set your environmental variables

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
     <key>Label</key>
     <string>my.startup</string>
     <key>ProgramArguments</key>
     <array>
       <string>sh</string>
       <string>-c</string>
       <string>
       launchctl setenv JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home
       launchctl setenv M2_HOME /Users/chrismanning/apache-maven-3.2.5
       </string>        
     </array>
     <key>RunAtLoad</key>
     <true/>
   </dict>
   </plist>
   

3. Save and restart your computer. This is the proper way to load Yosemite environmental variables

If you are using an older version of Mac OS X, see this answer
