我的机器上安装了maven 3.3.1和java 1.7,Windows 8.1。
MAVEN_HOME=C:\Program Files\Apache\apache-maven-3.3.1
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_75
Path=%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%MAVEN_HOME%\bin;
我尝试访问mvn命令行,在C:\ Users \ {myusername}>下,效果很好:
C:\Users\{myusername}>java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)
C:\Users\{myusername}>mvn -version
Apache Maven 3.3.1 (cab6659f9874fa96462afef40fcf6bc033d58c1c; 2015-03-13T13:10:2

Maven home: C:\Program Files\Apache\apache-maven-3.3.1\bin\..
Java version: 1.7.0_75, vendor: Oracle Corporation

Default locale: en_US, platform encoding: GBK
OS name: "windows 8.1", version: "6.3", arch: "amd64", family: "windows"
但当我将命令路径更改为D:,我机器中的另一个磁盘时,输出变为:
D:\>mvn --version

D:\>java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)
此外,当我使用Intellij创建maven项目时,就像quickstart一样,发生了类似的错误:
-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.[ERROR] Maven execution terminated abnormally (exit code 1)
我尝试过像mvn -version,mvn -d。但他们仍然无法工作。 有人可以帮忙吗?谢谢!
更新: 现在我的环境变量设置为:
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_75;
CLASSPATH=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;
M2_HOME=C:\Program Files\Apache\apache-maven-3.3.1;
MAVEN_HOME=C:\Program Files\Apache\apache-maven-3.3.1;
PATH=%JAVA_HOME%\bin;%M2_HOME%\bin;{others...}
问题仍然存在。
更新:
每当我在D:path中输入mvn命令后,命令行将只返回java提示;似乎忽略了mvn之后的所有事情。 就像这样:
D:\>mvn fewadsfe
Usage: java [-options] class [args...]

我也遇到了maven 3.3.1和Windows 7的问题,我在论坛中找到了这个answer。在此版本的maven中,在驱动器的根目录(c:\,d:\,...)中发出命令行存在问题。在任何其他目录上发出命令都可以。
答案 1 :(得分:6)
我遇到了与Maven 3.3.1相同的问题,但是当我尝试3.2.5版本时问题已修复。我不知道Windows 7/8和maven 3.3.1有什么问题。
答案 2 :(得分:2)
如前面的回复中所述,问题在于"-Dmaven.multiModuleProjectDirectory=C:\"
属性。如果删除了此属性的引号,则java命令可以正常工作。由于前面的反斜杠,似乎最终引用被视为路径的一部分。
在mvn.cmd
标记后为我:endDetectBaseDir
添加以下行。我正在使用maven 3.3.3。
IF "%MAVEN_PROJECTBASEDIR:~-1%"=="\" set MAVEN_PROJECTBASEDIR=%MAVEN_PROJECTBASEDIR%\
答案 3 :(得分:0)
在另一个驱动器上,您运行的命令为--
,而不是-
无法识别的命令,而是打印-help
。确保你正在使用
mvn -version
-Dmaven.multiModuleProjectDirectory系统属性未设置。
这是一个已知错误(更多详情here),现已已修复。按照错误跟踪器中的说明更新或修补当前安装。
