[英]mvn' is not recognized as an internal or external command
I have created these variables with their respective values, but even after doing this, command prompt is not recognizing mvn
command 我已经用它们各自的值创建了这些变量,但是即使这样做,命令提示符仍无法识别mvn
命令
System Variables: 系统变量:
M2_HOME
名称: M2_HOME
C:\\Program Files\\apache-maven-3.2.1
值: C:\\Program Files\\apache-maven-3.2.1
M2
名称: M2
%M2_HOME%/bin;
值: %M2_HOME%/bin;
path
名称: path
%JAVA_HOME%\\bin; %M2_HOME%\\bin;
值: %JAVA_HOME%\\bin; %M2_HOME%\\bin;
%JAVA_HOME%\\bin; %M2_HOME%\\bin;
From Maven documentation page : 从Maven文档页面 :
Maven, like many cross-platform tools, can encounter problems when there are space characters in important pathnames . 与许多跨平台工具一样,当重要路径名中包含空格字符时,Maven可能会遇到问题。 The instructions below will remind you of this for several particular items. 以下说明将提醒您一些特殊事项。
You have Maven installed in C:\\Program Files\\apache-maven-3.2.1
您已经在C:\\Program Files\\apache-maven-3.2.1
安装了Maven
Try to reinstall it to, for example, C:\\maven
, or change your current variable M2_HOME
to C:\\PROGRA~1\\apache-maven-3.2.1
尝试将其重新安装到例如C:\\maven
,或将当前变量M2_HOME
更改为C:\\PROGRA~1\\apache-maven-3.2.1
try : 尝试:
C:\\Program Files\\
per C:\\PROGRA~1\\
每个C:\\PROGRA~1\\
C:\\Program Files\\
替换C:\\Program Files\\
C:\\PROGRA~1\\
edit 编辑
this is my own config : 这是我自己的配置:
MAVEN_HOME="C:\Program Files\apache-maven-3.2.1"
PATH=XXX;%MAVEN_HOME%\bin;XXX
Hello I had the same problem and I figured it out that I was including some space characters on the "path" next to the ; 您好,我遇到了同样的问题,并且发现我在旁边的“路径”中包含一些空格字符。 just by removing the space character I was able to have everything working properly" 只需删除空格字符,我就能使一切正常工作”
this is the settings for my maven. 这是我的专家的设置。
name: MVN_HOME value: C:\\Program Files\\apache-maven-3.2.1 名称:MVN_HOME值:C:\\ Program Files \\ apache-maven-3.2.1
name: path -> add the following value(just the maven part) value: %JAVA_HOME%\\bin;%MVN_HOME%\\bin; 名称:path->添加以下值(仅是Maven部分):%JAVA_HOME%\\ bin;%MVN_HOME%\\ bin; -> this should have no spaces ->这个应该没有空格
I have a very difficult time to solve this problem. 我很难解决这个问题。 It did not work no matter how I set up the environment variables in the control panel of Win7. 无论我如何在Win7的控制面板中设置环境变量,它都不起作用。
My final solution is to set the variables via the cmd. 我的最终解决方案是通过cmd设置变量。
set M2_HOME "D:\Program Files\Maven\apache-maven-3.3.3"
set M2=%M2_HOME%\bin
set path=%path%;%M2%
I think you have a typo: 我认为您有错字:
change 更改
name: M2
value: %M2_HOME%/bin;
to 至
name: M2
value: %M2_HOME%\bin;
if it doesn't work change %M2_HOME%\\bin with the path. 如果不起作用,请更改路径%M2_HOME%\\ bin。 in this case: 在这种情况下:
C:\\Program Files\\apache-maven-3.2.1\\bin C:\\ Program Files \\ apache-maven-3.2.1 \\ bin
确保在系统变量而不是用户变量下设置路径。
In my case, for reasons I cannot explain, it made a difference to windows 7 if the MAVEN_HOME environment variable was defined in "System Variables" vs "User Variables". 就我而言,由于无法解释的原因,如果在“系统变量”与“用户变量”中定义了MAVEN_HOME环境变量,则对Windows 7有所不同。
I originally had both JAVA_HOME and MAVEN_HOME as "User Variables" and "Java -version" worked but windows could not find mvn (My path variable looked like this in both cases "Path=C:\\Program Files\\Java\\jre1.8.0_144\\bin;E:\\Clif\\Java\\apache-maven-3.6.0\\bin;") 我最初同时具有JAVA_HOME和MAVEN_HOME作为“用户变量”和“ Java -version”,但是Windows找不到mvn(在两种情况下,我的路径变量都看起来像这样:“ Path = C:\\ Program Files \\ Java \\ jre1.8.0_144 \\ bin; E:\\ Clif \\ Java \\ apache-maven-3.6.0 \\ bin;“)
Once I changed both Environment variables from "User Variables" to "System Variables" windows was able to find mvn. 一旦将两个环境变量从“用户变量”更改为“系统变量”,Windows便可以找到mvn。
I had the same issue. 我遇到过同样的问题。
What I did to resolve this is creating M2_HOME & MAVEN_HOME. 解决此问题的方法是创建M2_HOME和MAVEN_HOME。 Also, edit Path variable value. 另外,编辑路径变量值。
New -> C:\\Program Files\\Apache Software Foundation\\apache-maven-3.6.0\\bin 新建-> C:\\ Program Files \\ Apache Software Foundation \\ apache-maven-3.6.0 \\ bin
where Apache Software Foundation is a folder I created to extract the apache-maven-3.6.0-bin.zip file. 我在其中创建了Apache Software Foundation文件夹,以提取apache-maven-3.6.0-bin.zip文件。
Also, make sure Java is working fine and JAVA_HOME is properly set. 另外,请确保Java正常运行并且正确设置了JAVA_HOME。
I was using %MAVEN_HOME%
in the variable path
and it was giving problem, even though echo %MAVEN_HOME%
command was showing the right path. 我在变量path
使用了%MAVEN_HOME%
,即使echo %MAVEN_HOME%
命令显示了正确的路径,也给我带来了问题。
I changed it to C:\\Program Files\\apache-maven-3.6.1\\bin
in the path (Depends on your version of-course) and it worked like a charm. 我将其更改为路径中的C:\\Program Files\\apache-maven-3.6.1\\bin
(取决于您的课程版本),它的工作原理很吸引人。
