如果你知道groupId和aritifactId，你可以像这样生成下载url。

    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.2.3</version>
    </dependency>

http://central.maven.org/maven2/ch/qos/logback/logback-classic/

你会得到一个像这样的页面，选择你需要的版本，只是享受它!

如果您想手动找到任何工件的源jar文件，请转到特定工件的maven存储库位置，并在Files中单击“view All”。你可以找到源jar文件。

您可以在这个相关问题中找到相关信息:获取附加到Eclipse的源jar文件，以获得maven管理的依赖关系 如果你使用eclipse maven插件，那么使用'mvn eclipse:eclipse -DdownloadSources=true'

在Eclipse中

右键单击pom.xml 选择Run As -> Maven generate-sources 默认情况下，它将在.m2文件夹中生成源代码

Pre-Requisite:

Maven应该使用Eclipse进行配置。

Maven Micro-Tip: Get sources and Javadocs When you're using Maven in an IDE you often find the need for your IDE to resolve source code and Javadocs for your library dependencies. There's an easy way to accomplish that goal. mvn dependency:sources mvn dependency:resolve -Dclassifier=javadoc The first command will attempt to download source code for each of the dependencies in your pom file. The second command will attempt to download the Javadocs. Maven is at the mercy of the library packagers here. So some of them won't have source code packaged and many of them won't have Javadocs. In case you have a lot of dependencies it might also be a good idea to use inclusions/exclusions to get specific artifacts, the following command will for example only download the sources for the dependency with a specific artifactId: mvn dependency:sources -DincludeArtifactIds=guava

根据在Eclipse (Kepler)中查看Maven控制台，如果您试图在编辑器中从上述Maven依赖项打开一个类，而您还没有下载Maven依赖项的源代码，则将自动下载Maven依赖项的源代码。当您不想为所有依赖项获取源代码，但又不知道需要哪些依赖项时(而且您正在使用Eclipse)，这是非常方便的。

我最终使用了@GabrielRamierez的方法，但接下来将使用@PascalThivent的方法。
