问题描述
Maven 2位于存储库中，但不是Maven 3.如何正确安装Maven 3？我找到的指南并没有真正起作用。
我正在使用Natty，但我相信这不会改变任何东西。
最佳解决办法
Maven3是Ubuntu 12.04的默认设置(精确)
Maven2是11.10的最新版本。
maven3的PPA似乎相当稀少 – 这里是maverick的PPA – 尽管不是最新版本。
最好的建议是使用适用于您的发行版的稳定版本。
但是，如果您想自己保留up-to-date，下载代码并自行安装非常简单。
从here下载.tar.gz文件，并按照相同web-page上的安装指南
次佳解决办法
这是一个maven3 PPA，在64位Ubuntu 11.10上运行良好
sudo add-apt-repository ppa:natecarlson/maven3
sudo apt-get update && sudo apt-get install maven3
如果您已经从规范存储库安装了maven2，则不会替换它，但会为您提供mvn3二进制文件。
如果您希望使用名为mvn而不是mvn3的二进制文件，则只需执行以下操作：
sudo ln -s /usr/bin/mvn3 /usr/bin/mvn
第三种解决办法
问题是陈旧的，但金。我今天必须找到解决方案。开始了。不需要使用不安全的存储库，因为maven3已经包含在Ubuntu存储库中。 Ubuntu 14.04 LTS的解决方案如下：
-
sudo apt-get install maven -
sudo update-alternatives --config mvn
使用第2个命令，您需要设置使用的版本。您可以通过选择maven2不属于它的路径来区分正确的目录。
*0 /usr/share/maven2/bin/mvn 200 Auto-Modus
1 /usr/share/maven/bin/mvn 150 manueller Modus
2 /usr/share/maven2/bin/mvn 200 manueller Modus
在我的情况下，我必须选择1
使用发出的命令mvn -v，您可以验证设置是否成功以及是否选择了正确的版本。下面是一个返回值的示例。
~$ mvn -version
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.7.0_75, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: de_DE, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-45-generic", arch: "amd64", family: "unix"
希望这对你有所帮助。
第四种办法
我已经创建了一个新脚本，不仅应该安装Maven +将其添加到bin中，而是在使用Ubuntu作为VirtualBox guest虚拟机然后尝试安装现有的’.m2’和maven文件夹(可能/可能不包含现有设置)时启动。
如果它在Windows或Unix上运行，Maven保持不变，所以你可以在两者之间使用相同的Maven这是你的VirtualBox设置……
PS。请注意可以从/usr /local /bin安装/卸载共享文件夹的脚本的构建:)

第五种办法
这是maven3 PPA可以解决这个问题。
按照安装：
sudo apt-get purge maven maven2 maven3
sudo add-apt-repository ppa:andrei-pozolotin/maven3
sudo apt-get update && sudo apt-get install maven3
现在你已经安装了maven3：
