eclipse 下 maven 启动报错

Question

maven下载之后解压，之后添加了path，
控制台执行 mvn --version 也能正常显示。

在eclipse 中 创建一个demo项目后，运行run as -> maven install 时提示如下：

-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.

从网上没找到相应的解决问题，不知各位是否遇到过此问题

刚刚测了一下，用eclipse 自带的maven好使，apache下载的不好用

Answer 1

I found two posts on the Internet before to modify the eclipse.ini file and add
-Dmaven.multiModuleProjectDirectory=$M2_HOME, but it didn’t work. Later, I added this paragraph to the jdk parameters and it worked

Environment variables are configured like this

shellexport M2_HOME=/Users/mac/Applications/maven
export PATH=$M2_HOME/bin:$PATH 

Answer 2

Check whether the environment variables are configured correctly, and whether the eclipse中mavenconfiguration is correct

Answer 3

Did you install a plug-in for eclipse?
Have you modified the maven setting.xml warehouse path? There is also a designated place in eclipse. If it doesn’t work, try adding the environment variables when running

Answer 4

The configuration is wrong. Never use the built-in maven
