问题
I am trying to configure Maven on my Win 7 machine. I am following these steps: http://maven.apache.org/download.cgi I downloaded Maven into folder c:\Program Files\Apache Software Foundation\apache-maven-3.0.5\
I set all environmental variables as described in the URL above
JAVA_HOME = C:\Program Files\Java\jdk1.6.0_23
M2_HOME = c:\Program Files\Apache Software Foundation\apache-maven-3.0.5\
M2 = %M2_HOME%\bin
PATH = %M2%; C:\Program Files (x86)\SSH Communications Security\SSH Secure Shell; %JAVA_HOME%\bin ; C:\Program Files\Java\jdk1.6.0_23
But when I enter: C:\Users\Andrei>mvn --version
I get a :
Files\Java\jdk1.6.0_23"" was unexpected at this time.
Can you please help me with this issue? Let me know please if you need more details. Thanks in advance!

This one solved it for me: http://www.xinotes.net/notes/note/559/
It is a problem with how the JAVA_HOME path is being set.
Set the path without quotes like this:
set java_home=c:\Program Files\Java
Or using the 8 char syntax for folder names like this:
set java_home="c:\Progra~1\Java"

To solve the same issue
I did:
SET M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-3.2.3-bin\apache-maven-3.2.3
Then
SET JAVA_HOME=C:\Program Files (x86)\Java\jre7
And finally I added to the beginning of Path
SET Path=%JAVA_HOME%\bin;%M2_HOME%\bin;...
After exiting all my running cmd.exe and opened a new one I was able to do mvn --version with no problems.

I had the same problem, but the cause was M2_HOME variable defined as:
C:\apache-maven-3.2.2\bin
instead of
C:\apache-maven-3.2.2\
Also the JAVA_HOME should be to the java folder, and not to the \bin sub-folder.

I ran into a similar issue and the problem is with the presence of character "(" in the current directory path where maven is being run eg:- C:\Work(test)\Java-Project. I simply changed it to C:\Work\Java-Project and its working fine now.
For info I'm running Windows 10 with Maven V3.6.0
回答5:
Insert with windows GUI Environment Variable Configurations > System Variables : Name JAVA_HOME Path C:\Program Files (x86)\Java\jre7\ << with "\" in the end. no quotes.
kill process cmd.exe and re-open if it was opened. It worked to me.
回答6:
I had the same issue. I didn't have quotes around the values for M2_HOME or JAVA_HOME, but still got the error.
I moved %M2_HOME%\bin and %JAVA_HOME%\bin left in the path so that both occurred before any spaces in the path and the problem vanished.
