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

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!

要下载某些特定的源代码或javadoc，我们需要包括GroupIds -它是一个逗号分隔的值，如下所示

mvn dependency:sources -DincludeGroupIds=com.jcraft,org.testng -Dclassifier=sources

注意，分类器不是用逗号分隔的，要下载javadoc，我们需要使用分类器javadoc再次运行上述命令

mvn dependency:sources -DincludeGroupIds=com.jcraft,org.testng -Dclassifier=javadoc

为了调试，你也可以使用“Java反编译器”，如:JAD，并在运行中反编译源代码(尽管生成的源代码永远不会与原始源代码相同)。然后将JAD作为插件安装到Eclipse或您喜欢的IDE中。

你可以，如果他们被上传。通常它们被称为“frameworkname-version-source(s)”

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。
