我正在使用Ubuntu，需要从Maven 2升级到Maven3。有人可以帮我安装Maven 3吗？

这里有两个有关此特定主题的有用的出版物：

• 在Ubuntu 10.04 LTS服务器上安装Maven 3«试用与恐怖

• 从Ubuntu上的二进制deb安装maven 3«讨论

Nate Carlson制作的带有Maven 3的PPA：

https://launchpad.net/~natecarlson/+archive/maven3

它不在存储库中，根据我的经验，最好的解决方案是从apache.org下载该文件，将其解压缩/home/youruser/maven，然后按照此处的说明将其添加到您的路径中。

当然，请先卸载当前的Maven 2。

我开始为我正在从事的项目设置Ubuntu 12.10。需要Maven 3来设置系统，并且事实证明，那里的大多数文档都涉及如何将Maven安装到Ubuntu 12.04或更低版本。

如果您想深入了解apt-get方面的ubuntu内核，并在何处找到可用于在Ubuntu上安装的应用程序列表，则手动安装很有用。如果您遇到的问题与我当时使用Ubuntu 12.10时遇到的问题相同，它对于Ubuntu的最新版本（如Ubuntu 13.04等）也可能很有用。我发现的最佳文档是：

killertilapia.blogspot.com.au/2012/10/installing-maven-3-in-ubuntu-1204.html

手动安装：

我想到的整个过程如下：

1. 须藤-H gedit /etc/apt/sources.list

2. 在sources.list文件中添加以下行：

   deb http://ppa.launchpad.net/natecarlson/maven3/ubuntu精确主

   deb-src http://ppa.launchpad.net/natecarlson/maven3/ubuntu精确主

3. sudo apt-get更新&& sudo apt-get安装maven3

4. 须藤ln -s / usr / share / maven3 / bin / mvn / usr / bin / mvn

注意1：命令“ sudo add-apt-repository ppa：natecarlson / maven3”在我的Ubuntu上不起作用，必须运行“ sudo add-apt-repository -rm ppa：natecarlson / maven3”才能使我的apt-get正常工作再次。

警告2：感谢David，您需要在运行步骤4之前删除现有的指向早期版本的maven的符号链接。

自动安装：

sudo apt-get remove maven2
sudo apt-get update
sudo apt-get install maven

手动和自动安装的某些信息也可以在此处获得。

请尝试以下我编写的旨在对Linux通用的脚本，并检测VirtualBox的可能使用情况，并尝试从guest虚拟机挂载可能的文件（前提是已将它们设置为共享）：
