ngrinder通过获取环境变量maven.home来查找setting.xml， 可以启动的时候加参数-Dmaven.home=xxxxx来指定maven 的配置，手动给maven指定settings.xml的位置.前提是有装maven，且maven仓库指定到国内的，比如阿里云的。
经验证windows下面我们可以通过java -jar的方式启动ngrinder的控制台，且验证没有问题
当我们在linux虚拟机上使用这种方式带参数启动时，无法访问到ngrinder，原因未知，但直接java -jar是可以访问的
java -jar -Dmaven.home=/opt/apache-maven-3.5.4 ngrinder-controller-3.4.2.war
解决linux虚拟机上这个问题的方法，还是通过tomcat启动，不过在tomcat的bin目录下打开 catalina.sh ，然后把下面的内容放在文件的开头保存。记得修改成相应的maven路径。目前启动后还有报别的错，缺少一些jar包，可以通过手工导入，后续会补上
JAVA_OPTS="-Xms600m -Xmx1024m -XX:MaxPermSize=200m -Dmaven.home=/opt/apache-maven-3.5.4"windows也可以通过这个方式，在tomcat的bin目录下打开 catalina.bat,然后把下面的内容放在文件的开头保存。
set JAVA_OPTS=-Xms600m -Xmx1024m -XX:MaxPermSize=200m -Dmaven.home=E:\Myworkplace\apache-maven-3.5.0
