java - Maven根本不会运行

问题描述

我的环境变量是

JAVA_HOME = C:\Program Files\Java\jdk-10.0.2
M3_HOME = C:\Program Files\apache-maven-3.5.4
M3 = C:\Program Files\apache-maven-3.5.4
MAVEN_HOME = C:\Program Files\apache-maven-3.5.4
MAVEN_OPTS = C:\Program Files\apache-maven-3.5.4

我的 PATH 变量是

C:\Program Files\Java\jdk-10.0.1\bin
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
C:\Program Files\apache-maven-3.5.4\bin
C:\Windows\System32

我运行 java -verison 并且输出是

java version "10.0.2" 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

但是当我运行 mvn --version

Error: Could not find or load main class C:\Program
Caused by: java.lang.ClassNotFoundException: C:\Program

有人可以告诉我为什么 maven 不会运行

标签： javamaven-3

解决方案

Don't set the MAVEN_OPTS to C:\Program Files\apache-maven-3.5.4. Leave it empty.

This environment variable is meant to pass additional command line options to the JVM when it is running maven.
