但在终端中，我可以看到一个Maven版本：

在Ubuntu 20.0上，我也遇到了同样的问题，这是由于安装Maven引起的。
mvn在VSCode终端中运行，但分机未找到。我还尝试了另一个Stack Overflow答案：set maven extension settings in the user's settings.json但这一个仅适用于您可以在“Explorer”（VSCode的文件视图）内的“Maven”子部分中触发的命令。
对于Ubuntu，Maven需要从网站手动下载，因为Ubuntu APT包太旧了。
我的错误是编辑了
.bashrc脚本中的PATH变量，该变量仅在shell环境中可见。看起来这个扩展不能在shell环境中运行命令。当您为Ubuntu上的所有用户安装了Maven后，您可以在
/etc/environment中编辑PATH变量。如果它只安装在本地-在我的例子中它位于~/apache-maven/bin中-你可以通过将maven的目录路径-在我的例子中是$HOME/apache-maven/bin-添加到PATH中来将目录添加到~/.profile（或~/.pam_environment）中的PATH变量中。这对我很有效。
