intellij-idea - 无法执行目标 net.alchim31.maven :scala-maven-plugin:3. 2.0:compile (scala-compile)

Question

我正在尝试测试 Intellij IDEA scala maven project

当我运行时

测试

我收到此错误:

 Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.2.0:compile (scala-compile) on project neo4j-spark-connector: Execution scala-compile of goal net.alchim31.maven:scala-maven-plugin:3.2.0:compile failed: For artifact {null:null:null:jar}: The groupId cannot be empty.

这是 pom.xml我刚刚添加了这个依赖项:

 <dependency>
    <groupId>neo4j-contrib</groupId>
    <artifactId>neo4j-spark-connector</artifactId>
     <version>2.1.0-M4</version>
 </dependency>

这是错误日志:

我发现了和我一样的问题 here ，所以我升级了 maven-scala-插件到 3.3.3 而不是 3.2.0，之前的错误消失了
