Ubuntu 16 Java Develop环境快速搭建
- 安装JDK
1. 更新apt-get:
$ sudo apt-get update
2. 安装jdk:
$ sudo apt-get install openjdk-8-jdk
部分eclipse现只支持jdk8,且安装jdk9会有error,详见:
3. JDK版本切换:
$ sudo update-alternatives --config java
Differencebetween auto mode and manual mode in update-alternatives:
In Auto Mode, will select the generic name of the programautomatically based on the Priority value of the alternatives; The one with thehighest priority gets set as the generic name.
In Manual Mode, will set the generic name as the userselected alternative irrespective of the Priority value of the alternatives,hence the name "manual".
Java alternatives(sudoupdate-alternatives --config java) Change auto mode:
Make the priorityof /usr/lib/jvm/java-8-oracle/jre/bin/java higher that the rest to automatically enable it asdefault java binary.
$ sudoupdate-alternatives --install /usr/bin/java java/usr/lib/jvm/java-8-oracle/jre/bin/java 1100
4. 确认当前java 版本:
$ java -version
5. 添加环境变量:
$ sudo vim /etc/profile
# jdk
export JAVA_HOME=/usr/lib/jvm/java--openjdk-amd64
export JRE_HOME=${JAVA_HOME}/jre$ source /etc/profile
- 安装eclipse

Linux ubuntu 4.4.0-96-generic #119-Ubuntu SMP Tue Sep12 14:59:54 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
2. 官网下载:
http://www.eclipse.org/downloads/eclipse-packages/
3. 解压 (免安装版)
4. 运行“eclipse”
5. Window ->Perspective -> Customize Perspective 调整成自己习惯的perspective。
6. Lock to launcher 或者 添加图标。
