maven中下載jar包源碼和javadoc

1：Maven命令下載源碼和javadocs

當在IDE中使用Maven時如果想要看引用的jar包中類的源碼和javadoc需要通過maven命令下載這些源碼，然后再進行引入，通過mvn命令能夠容易的達到這個目的：

 

mvn dependency:sources mvn dependency:resolve -Dclassifier=javadoc

命令使用方法：首先進入到相應的pom.xml目錄中，然后執行以上命令：

 

第一個命令是嘗試下載在pom.xml中依賴的文件的源代碼。

第二個命令：是嘗試下載對應的javadocs

但是有可能一些文件沒有源代碼或者javadocs

reference

Executing mvn dependency:sources will force maven to download all sources of all jars in the project, if the sources are available (are uploaded in the repository where the artifact is hosted). If you want to download javadoc the command is mvn dependency:resolve -Dclassifier=javadoc

2：通過配置文件添加

打開maven配置文件 setting.xml文件(.../.m2/settings.xml) 增加如下配置：

<profiles>  
<profile>  
    <id>downloadSources</id>  
    <properties>  
        <downloadSources>true</downloadSources>  
        <downloadJavadocs>true</downloadJavadocs>             
    </properties>  
</profile>  
</profiles>  
  
<activeProfiles>  
  <activeProfile>downloadSources</activeProfile>  
</activeProfiles>  

3：配置eclipse

Window > Preferences > Maven and checking the "Download Artifact Sources" and "Download Artifact JavaDoc" options

如果是eclipse繼承環境，去掉mvn。
