Maven安装及测试
首先从http://maven.apache.org/download.html下载二进制安装包,最新的版本是3.0.2。
windows下安装:
1.将二进制包apache-maven-3.0.2-bin.zip解压至任意目录,比如C:\apache-maven-3.0.2
2.设置环境变量,M2_HOME=C:\apache-maven-3.0.2,并且在PATH变量里添加%M2_HOME%\bin
3.测试配置是否生效,控制台里输入mvn -v或mvn -version,显示如下信息,表示安装已经成功。
Maven的插件是在第一次加载时从仓库下载的,然后在本地保存一个副本,也就是说第一次需要联网到仓库去下载,新安装的Maven只包含内核,还不包含其他插件,我们可以使用describe目标去试着获取help插件的信息
因为是第一次加载,所以会看到很多下载信息,在插件下载完成之后,最后才打印出help插件的具体信息
上面的输出为help插件的Maven坐标,我们也可以看到新版本的Maven的9个目标,每个目标都做了说明,同时还包括了该插件的一个简要介绍、前缀等,如果你想要 Help 插件输出完整的带有参数的目标列表,只要运行带有参数full的help:describe目标就可以了
此时会输出非常详细的插件信息
该选项能让你查看插件所有的目标及相关参数。但是有时候这些信息显得太多了。这时候你可以获取单个目标的信息,设置mojo参数和plugin参数。下面的命令列出了Compiler插件的compile目标的所有信息
在Maven里面,一个插件目标也被认为是一个Mojo。比如上面我们看到help插件有system目标,所以我们可以这样来查看help:system下的output信息
windows下安装:
1.将二进制包apache-maven-3.0.2-bin.zip解压至任意目录,比如C:\apache-maven-3.0.2
2.设置环境变量,M2_HOME=C:\apache-maven-3.0.2,并且在PATH变量里添加%M2_HOME%\bin
3.测试配置是否生效,控制台里输入mvn -v或mvn -version,显示如下信息,表示安装已经成功。
