[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/NoGoalSpecifiedException
reason:
A specified goal is missing, and a goal data needs to be added to the project's pom.xml file.
Solution:
Find lib/model-builder-3.6.0.jar in the installation directory and choose to use the compressed package to open it.
Find pom.xml according to this directory META-INF——maven——org. apache .maven——maven-model-builder
Then find the first build and add the first line in it:<defaultGoal>compile</defaultGoal>
<build>
<defaultGoal>compile</defaultGoal>
</build>
