步骤一：
log-generator-1.0.jar放置到：
C:\Users\jieqiong\Desktop/log-generator-1.0.jar

步骤二：
执行以下命令
[C:\Users\jieqiong\IdeaProjects]$ mvn install:install-file
-Dfile=C:\Users\jieqiong\Desktop/log-generator-1.0.jar
-DgroupId=com.imooc.bigdata
-DartifactId=log-gen
-Dversion=1.0
-Dpackaging=jar

还是报错：

我的理解是log-generator-1.0.jar需要和主pom文件放在一起。
但是放在一起的话，也报错：
The parameters ‘file’ for goal org.apache.maven.plugins:maven-install-plugin:2.4:install-file are missing or invalid
