ubuntu linux 配置PATH JAVA PATH(解决双击不能启动eclipse的问题)

jdk,放在/opt下
于是我在/etc/bash.bashrc里添加：

[plain]
view plaincopyprint?

export JAVA_HOME=/opt/jdk1.7.0_06/ export PATH=$PATH:/opt/jdk1.7.0_06/bin/:/opt/apache-maven-3.0.4/bin/

export JAVA_HOME=/opt/jdk1.7.0_06/
export PATH=$PATH:/opt/jdk1.7.0_06/bin/:/opt/apache-maven-3.0.4/bin/

添加后，从terminal里启动eclipse是可行的，输入java javac也都可以，但是在文件夹里双击eclipse
却仍然提示：

[plain]
view plaincopyprint?

A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: /opt/eclipse/jre/bin/java java in your current PATH

A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following locations:
/opt/eclipse/jre/bin/java
java in your current PATH

又尝试在~/.bashrc里添加path

结果发现还是没有生效。

后来我用pstree来看，发现直接双击打开的程序都是在init下的。

[plain]
view plaincopyprint?

init─┬─NetworkManager─┬─dnsmasq
│ └─2*[{NetworkManager}]
...
├─dconf-service───2*[{dconf-service}]
├─<strong>eclipse</strong>───29*[{eclipse}]

init─┬─NetworkManager─┬─dnsmasq
│                └─2*[{NetworkManager}]
...
├─dconf-service───2*[{dconf-service}]
├─eclipse───29*[{eclipse}]

上边贴出来的是已经配置好的了，是在/etc/environment中补充了PATH，重启，就可以双击打开ECLIPSE了

总结：

UBUNTU可以设置PATH的地方很多，包括

/etc/profile

/etc/environment

/etc/bash.bashrc

~/.bashrc

只有在/etc/environment里设置，才能在init时候就生效
