maven之Aether，从本地 repo 获取 Artifact

有很多相关的问题

<dependency> 
    <groupId>com.jcabi</groupId> 
    <artifactId>jcabi-aether</artifactId> 
    <version>0.9</version> 
</dependency> 

当我需要从远程仓库获取 Artifact 时，它可以完美运行。
不幸的是，我找不到强制以太从本地 repo 中获取 Artifact 的方法。

它打印到控制台:

Artifact 在本地仓库中，但以太找不到它......
我做错了什么？

我的代码:
列表 远程仓库 , 文件 localRepoRoot 从 Maven 插件“注入(inject)”。此类从 maven-plugin 中使用。

MavenHelperAether(List<RemoteRepository> remoteRepos, File localRepoRoot) { 
        this.remoteRepos = remoteRepos 
        this.localRepoRoot = localRepoRoot 
    } 
 
    /** 
     * Resolves artifact using artifact coordinates 
     * @param artifactCoords is an artifact you need 
     * @param remoteLookup is ignored. It's a part of backward compatibility. 
     * 
     * @return {@link File} pointing to artifact 
     * */ 
    public File resolveArtifact(String artifactCoords, boolean remoteLookup = false){ 
        LOG.debug("resolving artifact $artifactCoords ... using localRepo[$localRepoRoot.absolutePath] and remoteRepos [$remoteRepos]") 
 
        def aether = new Aether(remoteRepos, localRepoRoot) 
        def artifact = new DefaultArtifact(artifactCoords) 
        Collection<Artifact> deps = [] 
        try{ 
            deps = resolveInRemoteRepositories(aether, artifact) 
            LOG.debug("Resolved artifact path ${deps.iterator().next().file.absolutePath }") 
            return deps.iterator().next().file 
        } 
        catch (DependencyResolutionException | IllegalArgumentException e){ 
            LOG.warn("Can't fetch $artifact from remote repos. Falling back to local repository...", e) 
            def localArtifact = resolveInLocalRepo(artifact) 
            if(localArtifact.exists()){ 
                return  localArtifact; 
            }else{ 
                throw new InstallerException("Can't locate artifact [$artifact] in local repo using path [$localArtifact.absolutePath]") 
            } 
        } 
    } 
 
    private Collection<Artifact> resolveInRemoteRepositories(Aether aether, DefaultArtifact artifact){ 
        LOG.debug("Trying to resolve $artifact in remote repositories...") 
        aether.resolve(artifact,JavaScopes.RUNTIME) 
    } 
 
    private  File resolveInLocalRepo(DefaultArtifact artifact){ 
        LOG.debug("Trying to resolve $artifact in local repository...") 
        def localRepoManager = new SimpleLocalRepositoryManager(localRepoRoot) 
        new File(localRepoManager.getPathForArtifact(artifact, true)) 
    } 

请您参考如下方法:

您可以创建本地远程仓库并将其提供给请求:

RemoteRepository local = new RemoteRepository.Builder("local", "default", "file:c:/Users/blah/.m2/repository").build();
RemoteRepository central = new RemoteRepository.Builder("central", "default", "http://central.maven.org/maven2/").build();

collectRequest.setRepositories(Arrays.asList(local, central));
