Java 抛出MojoFailureException不会导致；“构建失败”；运行插件时要显示的消息

我正在开发一个maven插件，它使用com.sun.tools.javadoc包

在我的抽象魔咒课上我有这个

@Mojo(name = "scan")
public class GreetingMojo extends AbstractMojo {

    public void execute() throws MojoExecutionException {

    Main.execute(new String[]{"-doclet", "my.plugin.SimpleCheck", "-docletpath"
            , "."
            , "-sourcepath"
            , "./src/main/java"
            , "-subpackages"
            , "com.my.system"});
    }
}

在我的SimpleCheck.java文件中，我抛出了异常

public class SimpleCheck {
    public static boolean start(RootDoc root) throws IOException, ParseException, MojoFailureException {
        throw new MojoFailureException("test");
    }
}

[ERROR] Failed to execute goal my.plugin:my-maven-plugin:1.0-SNAPSHOT:scan (default-cli) on project abcmanager: test throw in GreetingMojo -> [Help 1]
[ERROR] 

正如预期的那样，异常被抛出

javadoc: error - In doclet class my.plugin.SimpleCheck,  method start has thrown an exception java.lang.reflect.InvocationTargetException
org.apache.maven.plugin.MojoFailureException: test

为什么构建仍然是成功的。抛出的异常不应该使构建失败吗。在MojoFailureException的文档中，它说

插件执行期间发生的异常（例如编译失败）。 引发此异常会导致显示“生成失败”消息

为什么在这种情况下它没有发生

注意：我试图在GreetingMojo.java类中抛出异常。然后，在引发异常后，生成失败

public class SimpleCheck {
    public static boolean start(RootDoc root) throws IOException, ParseException, MojoFailureException {
        throw new MojoFailureException("test");
    }
}
