Just to use in eclipse you can add this in Window -> Preferences -> Java -> Build Path -> Classpath Variables.
只是为了在 Eclipse 中使用，您可以在 Window -> Preferences -> Java -> Build Path -> Classpath Variables 中添加它。
Just add new variable with name MAVEN_HOME.
只需添加名为 name 的新变量MAVEN_HOME。
But for executions you need to set in in Run/Debug configuration - probably that's what you need.
但是对于执行，您需要在运行/调试配置中进行设置 - 可能这就是您所需要的。
whereis maven
is about directory, and
是关于目录，和
whereis mvn
is about executable file.
是关于可执行文件的。
For .bashrc:
对于 .bashrc：
MAVEN_HOME=/usr/share/maven
export MAVEN_HOME

Don't set the MAVEN_HOMEin bashrcfile but set it in the Environment tab of the launcher configuration of Eclipse.
不要设置MAVEN_HOMEinbashrc文件，而是在 Eclipse 启动器配置的环境选项卡中设置它。
The .bashrc file is for the bash environment
.bashrc 文件用于 bash 环境

Basically invoker.setMavenHome(MAVEN_HOME);this needs the home directory where you have installed maven. If you need to find where is the home directory of maven. You can you use following approaches as you tried.
基本上invoker.setMavenHome(MAVEN_HOME);这需要您安装 maven 的主目录。如果需要查找maven的主目录在哪里。您可以尝试使用以下方法。
whereis maven
This will be showing where is the location which maven has been installed into your computer.
这将显示 Maven 安装到您的计算机的位置。
maven: /etc/maven /usr/share/maven
