1,下載Eclipse(http://www.eclipse.org/downloads/)的最新版本,因爲我這裏下載的是eclipse-inst-linux64.tar.gz安裝版本。因此跟其餘教程不太同樣:html
2,解壓Eclipse到目錄/opt/,以供全局使用。java
3,在目錄:/opt/eclipse/下,能夠看到一個可執行文件,雙擊便可運行:linux
4,建立桌面快捷方式,以下:vim
1,在終端中執行以下命令bash
gksudo gedit /usr/share/applications/eclipse.desktop
2,粘貼並保存以下內容oracle
[Desktop Entry] Name=Eclipse 4 Type=Application Exec=/opt/eclipse/eclipse Terminal=false Icon=/opt/eclipse/icon.xpm Comment=Integrated Development Environment NoDisplay=false Categories=Development;IDE; Name[en]=Eclipse
參考:http://blog.csdn.net/snowdream86/article/details/6677450app
1, 下載jdk:(http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html)eclipse-inst-linux64.tar.gz eclipse
2, 解壓安裝:解壓eclipse-inst-linux64.tar.gz 到/usr/lib/jvm/目錄下jvm
3,設置環境變量:vim ~/.bashrc ,並讓其當即生效:source ~/.bashrcide
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_79 export JRE_HOME=${JAVA_HOME}/jre export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib export PATH=${JAVA_HOME}/bin:$PATH
4, 配置默認JDK版本:
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_79/bin/java 300 sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0_79/bin/javac 300 sudo update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/jdk1.7.0_79/bin/jar 300 sudo update-alternatives --install /usr/bin/javah javah /usr/lib/jvm/jdk1.7.0_79/bin/javah 300 sudo update-alternatives --install /usr/bin/javap javap /usr/lib/jvm/jdk1.7.0_79/bin/javap 300
sudo update-alternatives --config java
系統會列出各類JDK版本,以下所示:
有 3 個候選項可用於替換 java (提供 /usr/bin/java)。 選擇 路徑 優先級 狀態 ------------------------------------------------------------ 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 自動模式 1 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 手動模式 2 /usr/lib/jvm/jdk1.7.0_79/bin/java 300 手動模式 * 3 /usr/local/java/jdk1.6.0_45/bin/java 1 手動模式 要維持當前值[*]請按回車鍵,或者鍵入選擇的編號:2 update-alternatives: using /usr/lib/jvm/jdk1.7.0_79/bin/java to provide /usr/bin/java (java) in 手動模式
5, 測試:java -version
java version "1.7.0_79" Java(TM) SE Runtime Environment (build 1.7.0_79-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
