无法执行目标org.codehaus.mojo：exec-maven-plugin

Question

我试图执行一个java文件，当我这样做时，我收到了这条消息：

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.2:java (default-cli) on project PruebaMaven: An exception occured while executing the Java class. null: InvocationTargetException: NullPointerException -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.2:java (default-cli) on project PruebaMaven: An exception occured while executing the Java class. null

我有这个pom.xml但它还没有工作

我也在这个论坛上看过其他帖子，但是他们不适应我的确切情况，或者他们不起作用。感谢。
