What to do if you can't open eclipse in a Mac environment

There is a big possibility that eclipse (what tools Eclipse:java development should use) does not specify the JDK version (how to install JDK: How to install and configure the JDK) path, boot time is not loaded to the JDK caused by the flash back. Don't say much nonsense, just say the solution.

1. Open $ECLIPSE _home/eclipse.app/contents/macos/eclipse.ini file:

Right-click or CTRL + Tap the Eclipse application in the Finder, then click " Show Package Contents " and go to the directory contents/macos/to find it.
2 . Use ls-ltr/library/java/javavirtualmachines/ to list the paths for each JDK version that you have installed, and then specify it in the Eclipse.ini file Like what:

-vm/library/java/javavirtualmachines/jdk1.8.0_25.jdk/contents/home/bin/java

the system defaults to the following:

/system/library/frameworks/javavm.framework/versions/current/commands/java

The Query method pointed to by the query java_home is attached as follows:

/usr/libexec/java_home-v

You can see where all the java_home point to:

Matching java Virtual Machines (4): 1.8.0_40, x86_64: "Java SE 8"/library/java/javavirtualmachines/jdk1.8.0_40.jdk/ contents/home1.7.0_79, x86_64: "Java SE 7"/library/java/javavirtualmachines/jdk1.7.0_79.jdk/contents/home1.6.0_65- b14-468, x86_64: "Java SE 6"/library/java/javavirtualmachines/1.6.0.jdk/contents/home1.6.0_65-b14-468, i386: "Java SE 6 "/library/java/javavirtualmachines/1.6.0.jdk/contents/home/library/java/javavirtualmachines/jdk1.8.0_40.jdk/ Contents/home

Display the file information as follows:

Ls-ltr/usr/libexec/java_home

Results:

Lrwxr-xr-x 1 root Wheel 10:36/usr/libexec/java_home-/system/library/frameworks/javavm.framework/versions /current/commands/java_home
