我必须使用此命令从命令行运行 Maven 项目并且运行良好：
mvn -Dexec.args="-classpath %classpath com.mycompany.serverrds.serverMainClass" -Dexec.executable="C:\Program Files\Java\jdk1.8.0_191\bin\java.exe" -Dfile.encoding=UTF-8 org.codehaus.mojo:exec-maven-plugin:1.2.1:exec
我创建了一个.bat文件来快速运行命令，但是出现错误；
我的.bat文件组成如下：
@echo_off
cd c:\xyz\
"C:\Program Files\apache-maven-3.6.0\bin\mvn.cmd" -Dexec.args=-classpath %classpath com.mycompany.serverrds.serverMainClass -Dexec.executable="C:\Program Files\Java\jdk1.8.0_191\bin\java.exe"
其中“c:\dev\mavproj”是maven项目所在的目录，.bat文件名为test.bat。
我收到此错误：“命令的语法不正确”。
好吧，我创建了新的文件 .bat 并且只插入
"C:\Program Files\apache-maven-3.6.0\bin\mvn.cmd"
并且mvn命令执行成功。
mvn.cmd 的内容：

我哪里错了？
提前致谢。
答案1
我已经解决了使用 Sysinternal 和 Netbeans 的 ProcessExplorer 的问题：我在 netbeans 中运行程序并将命令提示符命令复制为：
在我调整了更改 maven 目录的命令后，一切正常。
新的bat文件是：
cd "C:\sviluppo_software\rdsServerMav"
"cmd" /c ""C:\Program Files\apache-maven-3.6.0\bin\mvn.cmd" -Dexec.args="-classpath %%classpath com.mycompany.serverrds.serverMainClass" -Dexec.executable="C:\Program Files\Java\jdk1.8.0_152\bin\java.exe" -Dfile.encoding=UTF-8 org.codehaus.mojo:exec-maven-plugin:1.2.1:exec"
注意类路径上的“%%”以正确执行该 bat 文件。
