以编程方式获取Maven工件 [英] Fetching Maven artifacts programmatically

问题描述

我正在寻找可用于从远程存储库检索Maven工件的Java API。到目前为止，我发现了 Eclipse Ather ，但是由于我的需要，我看起来很复杂，所以我正在寻找一些东西更简单。

I'm looking for a Java API which can be used to retreive Maven artifacts from a remote repository. I've found Eclipse Ather so far but it looks over complicated for my needs so i'm seeking for something more simple.

我需要的是：

• 我必须指定远程Maven存储库的位置


• 我喜欢根据它的groupId + artifactId + version
获取工件

• API必须提供当前的远程（请考虑SNAPSHOT工件，这些工件是定期生成的，以便它们在其版本中生成部分）


• 返回工件的位置，优先使用HTTP URL取自己的，例如Apache HTTP客户端）


• 可选地，检索作为所请求的依赖项的工件。

• I have to specify the location of the remote Maven repository
• I like to fetch an artifact based on it's groupId + artifactId + version
• The API have to provide the current remote version of the artifact (think about SNAPSHOT artifacts which are regularly built so they have a generated part in their versions)
• Return the location of the artifact, a HTTP URL is preferred (i'll fetch it on my own with eg. Apache HTTP Client)
• Optionally retreive the artifact's which are the dependants of the requested one.

推荐答案

jcabi-aether 可能会帮助你（我是开发人员）。它是Aether的简单包装，可以让您找到Maven工件的所有传递依赖关系：

jcabi-aether may help you (I'm a developer). It's a simple wrapper around Aether, that lets you find all transitive dependencies of a Maven artifact:

File repo = this.session.getLocalRepository().getBasedir();
Collection<Artifact> deps = new Aether(this.getProject(), repo).resolve(
  new DefaultArtifact("junit", "junit-dep", "", "jar", "4.10"),
  JavaScopes.RUNTIME
);

因此，您需要提供的所有输入都是：

Thus, all you need to provide as an input is:

• 本地回购位置，作为目录名称


• repote存储库列表（ MavenProject＃getRemoteRepositories（） code>）


• 工件的Maven坐标


• 要查找的Maven范围

• Local repo location, as a directory name
• List of repote repositories (MavenProject#getRemoteRepositories())
• Maven coordinates of the artifact
• Maven scope to look for

找到的每个依赖关系的绝对路径可以获取为 Artifact＃getPath（）

Absolute paths of every dependency found can be obtained as Artifact#getPath()
