Java Environment MAVEN environment configuration under MAC

Under the Mac configuration of the Java environment and MAVEN environment, found that the network configuration methods are different, tried a variety of, now record my configuration after the summary of the method

Java Environment Configuration

1. Download the JDK and follow the prompts to install

I'm under 1.8. Version 0,: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

2. View the installed JDK and path

Command line terminal input:

/usr/libexec/java_home-v    //view installed JDK and path

Output:

Matching java Virtual machines (1):    1.8"java SE 8" /library /java/javavirtualmachines/jdk1. 8. 0_111.jdk/contents/home

The/library/java/javavirtualmachines/jdk1.8.0_111.jdk/contents/home is the installation path of the JDK.

3. Configure Java_home

Terminal input:

1. CD ~//Enter the user root directory2.Touch. Bash_profile3. Vim. Bash_profile//edit. Bash_profile4.

Press ESC to exit Insert mode, enter: Wq Save exit6. source. bash_profile//Update configuration file

4. At this point, the Java development environment is configured

Terminal input: Echo $JAVA _home, if the path you just configured is output, the configuration is successful.

PS: It must be explained that this configuration method only applies to user environment variables, if the system updates, the previous configuration may be invalid, if you want to permanently change the configuration in the/etc directory in the profile file
