Mac OS X 10.10 Yosemite Install Java, JDK, MySQL, maven, idea

Mac OS X Yosemite was officially released on October 17, 2014.

As a Java developer, early adopters installed the latest version of the first time.

and the previous OS X system is still a lot different. Here's a note on the Java development environment.

1. JDK Installation

By default, the 10.10 system also does not have a JDK installed, nor does it automatically download the JDK to an Apple server.

There are two options, one is to download the latest version of the JDK (1.8.0_25) on the Oracle website, and the other is to download the 10.9 1.6.0_65 version of the JDK, which is officially provided by Apple,

1.6.0_65 version: http://support.apple.com/kb/DL1572

2. mysql Installation

To the website of MySQL download for 10.9 version and above the DMG or tar files, I download the dmg file here, double-click installation, note that during the installation process, you need to change the installation options, the [Startup Item] option is removed, or you will be prompted to install failure, the main reason is " MySQL Start on Restart script fails ".

Since MySQL is installed, the auto-start option is not selectable, resulting in MySQL not starting automatically. The solution is as follows:

Create a new plist file with the name: Com.mysql.plist and edit its contents as follows:

<?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>com.mysql</string>                <key>ProgramArguments</key>                <array>                        <string>/usr/local/mysql/bin/mysqld_ safe</string>                </array>                <key>RunAtLoad</key>                <true/>                <key> keepalive</key>                <false/>        </dict></plist>

Once saved, move it to (or make a soft link) to the/library/launchdaemons directory and execute the command.

Launchctl load-w Com.mysql.plist

So far, MySQL can start up as the system starts.

3. MAVEN Installation

To the Apache official website to download the latest version, unzip to the specified location, I specify here to extract the location of the/usr/local directory;

Edit the ~/.bash_profile file and add the contents to the file:

Export java_home= "/library/java/javavirtualmachines/jdk1.8.0_25.jdk/contents/home" Export path= "$JAVA _home/bin:$ PATH "Export m2_home="/usr/local/maven "Export m2=" $M 2_home/bin "Export path=" $M 2: $PATH "Export path="/usr/local/mysql /bin: $PATH "

After saving, execute

source. bash_profile

You can now run

MVN--version

If the test is successfully installed, the version information of MAVEN will be printed successfully

$ mvn--versionapache maven 3.2.3 (33F8C3E1027C3DDDE99D3CDEBAD2656A31E8FDF4; 2014-08-12t04:58:10+08:00) maven Home:/ Usr/local/mavenjava version:1.8.0_25, Vendor:oracle Corporationjava home:/library/java/javavirtualmachines/ Jdk1.8.0_25.jdk/contents/home/jredefault LOCALE:ZH_CN, platform Encoding:utf-8os name: "Mac OS X", Version: "10.10", arc H: "X86_64", Family: "Mac"

4. Intellij Idea Installation

If the JDK version installed earlier is 1.6, this may not be a problem;

If you install a JDK version of 1.8, you will need to change it in the following steps:

1, first drag and drop IntelliJ idea into the/applications directory (installation);

2, double-click IntelliJ Idea, run, you will be prompted to run the JRE environment, and prompted to download the Apple official website; Note: I have installed 1.8 here, why also install jdk1.6 it? This is completely unnecessary, how to do? Go down ...

3. Right-click on IntelliJ idea.app, display package contents->contents->info.plist, apply text or default Xcode open, find

<string>1.6*</string>

Change 1.6 to 1.8 to save the exit. Open IntelliJ Idea,ok again, success.

4, open the relevant parameters can be set.
