[英]Maven artifact cannot be resolved; attempting to resolve artifact from the wrong repository
[英]How can I resolve an artifact from the Maven repository within a plugin?
在上一个问题中,我得到了从Maven存储库下载工件的答案 。 这对我来说效果很好,但是我需要阅读MavenProject中下载的工件。
对我来说,读取插件中下载的工件的MavenProject的最佳方法是什么?
您可以使用MavenProjectBuilder来解决工件,并将下载的pom读取到MavenProject中。 buildFromRepository()方法将从远程存储库获取工件(如果需要),因此在阅读之前无需下载它。
这些是对先前答案解决maven项目所需的更改:
//other imports same as previous answer
import org.apache.maven.project.MavenProject;
import org.apache.maven.project.MavenProjectBuilder;
import org.apache.maven.project.ProjectBuildingException;
/**
* Obtain the artifact defined by the groupId, artifactId, and version from the
* remote repository.
*
* @goal bootstrap
*/
public class BootstrapAppMojo extends AbstractMojo {
/**
* Used to resolve the maven project.
*
* @parameter expression=
* "${component.org.apache.maven.project.MavenProjectBuilder}"
* @required
* @readonly
*/
private MavenProjectBuilder mavenProjectBuilder;
//rest of properties same as before.
/**
* The target pom's version
*
* @parameter expression="${bootstrapVersion}"
* @required
*/
private String bootstrapVersion;
public void execute() throws MojoExecutionException, MojoFailureException {
try {
Artifact pomArtifact = this.factory.createArtifact(
bootstrapGroupId, bootstrapArtifactId, bootstrapVersion,
"", bootstrapType);
MavenProject project = mavenProjectBuilder.buildFromRepository(
pomArtifact, this.remoteRepositories, this.localRepository);
//do something with the project...
} catch (ProjectBuildingException e) {
getLog().error("can't build bootstrapped pom", e);
}
}
}
