根据maven的官方教程，将外部jar安装到本地存储库，但失败了

Question

the command I used(according to maven's official tutorial: maven ):

mvn install:install-file -Dfile=algs4-1.0.4.jar -DgroupID=edu.princeton.cs -DartifactID=algs4 -Dversion=1.0.4 -Dpackaging=jar

---

the error info told groupID and artifactID are missing,so I try to modify the command:

mvn install:install-file -Dfile=algs4-1.0.4.jar -groupID=edu.princeton.cs -artifactID=algs4 -Dversion=1.0.4 -Dpackaging=jar

you know,that's even worse.

I also try some solution from some answers here,they don't work either.

• expected result is,you know,install the jar.
• actual results is:

Answer 1

拼错了groupId和artifactId作为groupID和artifactID 。
