What did you set up exactly? Did you setup PATH like this (or something equivalent):
你具体是怎么设置的？您是否像这样设置了 PATH（或类似的东西）：
export PATH=$PATH:...:$M2_HOME/bin
If yes, did you logout and login again? According to the bash manpage:
如果是，您是否注销并重新登录？根据 bash 联机帮助页：
When bash is invoked as an interactive login shell, or as a non-interactive shell with the
--loginoption, it first reads and executes commands from the file/etc/profile, if that file exists. After reading that file, it looks for~/.bash_profile,~/.bash_login, and~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The--noprofileoption may be used when the shell is started to inhibit this behavior.
...
When an interactive shell that is not a login shellis started, bash reads and executes commands from/etc/bash.bashrcand~/.bashrc, if these files exist. This may be inhibited by using the--norcoption. The--rcfilefile option will force bash to read and execute commands from file instead of/etc/bash.bashrcand~/.bashrc.
当 bash 作为交互式登录 shell或带有
--login选项的非交互式 shell调用时 ，它首先从文件中读取并执行命令/etc/profile（如果该文件存在）。读取该文件后，它会按该顺序查找~/.bash_profile、~/.bash_login、 和~/.profile，并从第一个存在且可读的命令中读取和执行命令。--noprofile当 shell 启动时可以使用该选项来禁止这种行为。
...
当一个不是登录 shell的交互式 shell启动时，bash 读取并执行来自/etc/bash.bashrc和 的命令~/.bashrc（如果这些文件存在）。这可以通过使用--norc选项来禁止。这--rcfilefile 选项将强制 bash 从 file 而不是/etc/bash.bashrcand 读取和执行命令~/.bashrc。
As you can see, commands from .profileare not executed for a non-login shell (the type of shells you open after logging in). So you have to logout/login or to source the file manually to take your setup into account. See this blog postfor more details.
如您所见，来自.profile非登录 shell（登录后打开的 shell 类型）的命令不会执行。因此，您必须注销/登录或手动获取文件以将您的设置考虑在内。有关更多详细信息，请参阅此博客文章。
