Download JDK Source code for Mac OS X

The JDK source code is packaged in a src.jar, and should be in the JDK/Home folder. However, some JDK versions in Mac OSX didn’t include the source code or Javadoc.

Try find it :

sudo find / -name src.jar

If you couldn’t find the src.jar, then get it from Apple developer website.

1. Download from Apple Developer

Go https://developer.apple.com/downloads/index.action , sign in with your Apple ID.

Download the “Java for OS X 2013-0* Developer Package“, it contains JDK runtime, source code and Javadoc, install the downloaded *.dmg and follow the wizard guide to finish the installation.

2. Find JDK Source Code

After the installation, the JDK source code should be found in following location :

/Library/Java/JavaVirtualMachines/jdk_version.jdk/Contents/Home/src.jar
##example
/Library/Java/JavaVirtualMachines/1.6.0_43-b01-447.jdk/Contents/Home/src.jar
