　　从 http://www.eclipse.org/downloads/packages/eclipse-ide-cc-developers/neon2 下载 eclipse-cpp-neon-2-linux-gtk-x86_64.tar.gz，解压安装至目录 /opt/，运行 /opt/eclipse/eclipse，报错：

看起来是需要 java 1.8。

查看java版本：

$ java -version

java version "1.7.0_111"
OpenJDK Runtime Environment (IcedTea 2.6.7) (7u111-2.6.7-2~deb8u1)
OpenJDK 64-Bit Server VM (build 24.111-b01, mixed mode)

查查是哪里的java命令：

$ which java
/usr/bin/java
$ ll /usr/bin/java
lrwxrwxrwx 1 root root 22 Jan 25 01:37 /usr/bin/java -> /etc/alternatives/java
$ ll /etc/alternatives/java
lrwxrwxrwx 1 root root 46 Jan 27 15:36 /etc/alternatives/java -> /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java

上网搜索/etc/alternatives/java，找到 http://unix.stackexchange.com/questions/100732/i-deleted-etc-alternatives-java，根据其中的说法，执行以下命令以切换至1.8版：

$ sudo update-alternatives --set java /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

本质上它完成的任务是：

ln -s /usr/lib/jvm/jdk1.7.0_45/jre/bin/java /etc/alternatives/java

此时再启动eclipse，运行正常。
