Question

我正在创建一个maven插件，MVN clean install build成功但是plugin.xml没有生成。

@Mojo( name = "cover",  defaultPhase = LifecyclePhase.POST_INTEGRATION_TEST)
public class RunCoverage extends AbstractMojo
{

    @Parameter( property = "cover.wadl", defaultValue = "test")
    private String wadl;

    @Parameter( property = "cover.endpoints",defaultValue = "test")
    private String endpoints;

    @Override
    public void execute() throws MojoExecutionException
    {
        <somecode>
    }
}

pom.xml是

Maven clean install不会生成plugin.xml

在依赖项目中使用时，我收到以下错误

无法解析it.gruppopam.common的插件描述符：end-point-test-coverage：1（/home/d/.m2/repository/it/common/end-point-test-coverage/1/end -point-test-coverage-1.jar）：在META-INF / maven / plugin.xml中找不到插件描述符 - ＆gt; [帮助1] [错误]

Answer 1

首先，我会尝试将包装类型设置为maven-plugin，而不是默认值jar。此外，我建议使用更多最新版本的插件（maven-compiler-plugin：3.1）并使用更新版本的maven-plugin-api（3.0？但不是2.0）。

Answer 2

你必须记得在你的pom.xml中将它改为：

<packaging>maven-plugin</packaging>

默认情况下：

<packaging>jar</packaging>

maven插件描述符未生成
