我刚刚下载了Maven 3.3.9
我的变数是：
M2_HOME C:\Users\apragnya\Downloads\apache-maven-3.3.9\apache-maven-3.3.9
JAVA_HOME C:\Program Files\Java\jdk1.8.0_45
和我的路径
C:\ProgramData\Oracle\Java\javapath;C:\Program Files\Common Files\Microsoft Shared\Microsoft Online Services;C:\Program Files (x86)\Common Files\Microsoft Shared\Microsoft Online Services;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\%JAVA_HOME%\bin%M2%%CATALINA_HOME%\bin;C:\Dwimperl\perl\bin;C:\Dwimperl\perl\site\bin;C:\Dwimperl\c\bin;C:\Users\apragnya\Downloads\apache-maven-3.3.9\apache-maven-3.3.9\bin;%JAVA_HOME%\bin;
