Question

我正在开发一个使用 com.sun.tools.javadoc 包的maven插件。

在我的抽象mojo类中，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，我抛出异常。

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

正如预期的那样，抛出异常。

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。不应该抛出抛出的异常使构建失败。在 MojoFailureException 的文档中，它说，

执行插件期间发生的异常（例如编译失败）。抛出这个例外导致＆＃34; BUILD FAILURE＆＃34;要显示的消息。

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。抛出异常后构建失败了。

抛出MojoFailureException不会导致＆＃34; BUILD FAILURE＆＃34;运行插件时显示的消息
