如何解决maven插件内的maven依赖关系？

Question

我尝试使用带有标志 resolveTransitively=true 的 ArtifactResolver.resolve(ArtifactResolutionRequest) ，我的项目的分离模块需要 10 分钟。

ArtifactResolutionRequest request = new ArtifactResolutionRequest()
        .setArtifact( project.getArtifact() )
        .setArtifactDependencies( project.getDependencyArtifacts() )
        .setLocalRepository( localRepository )
        .setManagedVersionMap( project.getManagedVersionMap() )
        .setForceUpdate(false)
        .setResolveTransitively(true)
        .setOffline(true)
        .setListeners(listeners);
result = artifactResolver.resolve(request);

如果我只是用 mvn 构建它，需要大约 4 秒。

maven如何在编译前解决所有传递依赖以及如何在代码中使用它？

//项目的单独模块大量使用父级，导入依赖项，最终拥有 350 个依赖项。那么可能是maven build 减少了一些处理步骤或者ArtifactResolver 额外做了一些事情吗？

这是我用来解析工件并获取对其的文件引用的代码：

// get maven artifact representing this mojo artifact
org.apache.maven.artifact.Artifact ma = ...; // create artifact reference
// resolve the maven artifact
try {
    resolver.resolve(ma, remoteRepositories, localRepository );
} catch (ArtifactNotFoundException ex) {
    throw new MojoExecutionException("could not find deploy artifact ["+a+"]", ex);
} catch (ArtifactResolutionException ex) {
    throw new MojoExecutionException("could not resolve deploy artifact ["+a+"]", ex);
}
File maFile = ma.getFile();

存储库引用是类级别的属性，通过 Maven 中的依赖项注入来解析。你只需要在你的类中声明它们：

/** 
 * @parameter default-value="${localRepository}" 
 * @readonly
 * @required
 */
protected ArtifactRepository localRepository;

/** 
 * @parameter default-value="${project.remoteArtifactRepositories}" 
 * @readonly
 * @required
 */
protected java.util.List<ArtifactRepository> remoteRepositories;
