I have Installation B, and now Installation C is linked to Installation A.įor using eclipse, I had to make Compiler Compliance level to 1.6 to use it (from the help Unsupported major.minor version 51.0). Is there any way to use just one JDK 1.7 for Mavericks by removing two of them safely?Īfter some setup and test, I have only one Java (1.6) installed.Lrwxr-xr-x 1 root wheel 74 Jan 15 09:12 -> /System/Library/Frameworks/amework/Versions/Current/Commands/java When I invoked java from command line, it points to Installation A. I found that I can easily remove Installation C, however I'm not sure if this is OK. Installation C /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin/java Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode) Installation B /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode) Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Installation A /System/Library/Frameworks/amework/Versions/Current/Commands/java Now I have three java binaries installed in my computer. Installing Java on OS X 10.9 (Mavericks).I downloaded JDK for Mac OS X 10.9.1 from Oracle, but I had to install another Java from Apple site once more, as I couldn't launch eclipse with it.
