如何获取 Mojo.execute() 中的 ${basedir} 值（或其他属性）？

Question

我正在尝试获取 Mojo 中 ${basedir} 的值。我以为我可以将其视为正常系统属性但

System.getProperty("basedir")

returns null.

public void execute() throws MojoExecutionException, MojoFailureException {
    String baseDir = ???
}

Answer 1

这是通过注入 MavenProject and invoking the getBaseDir() 方法完成的，像这样：

public class MyMojo extends AbstractMojo {

    @Parameter(defaultValue = "${project}", readonly = true, required = true)
    private MavenProject project;

    public void execute() throws MojoExecutionException, MojoFailureException {
        String baseDir = project.getBaseDir();
    }

}

@Parameter is used to inject the value ${project}, which resolves 从 Maven 会话构建的当前项目。

Using annotations 需要以下对 Maven 插件的依赖：

<dependency>
  <groupId>org.apache.maven.plugin-tools</groupId>
  <artifactId>maven-plugin-annotations</artifactId>
  <version>3.5</version>
  <scope>provided</scope> <!-- annotations are needed only to build the plugin -->
</dependency>
