MAVEN_OPTS和CATALINA_OPTS的作用
MAVEN_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=n
CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8787
他们的目的都是一样的，就是远程调试。无非一个是maven的远程调试，一个是tomcat的远程调试。
更具体的说明如下，以MAVEN_OPTS为例：
After setting this property, run "maven cactus:test" (or whatever goal to debug) and it will block, waiting for a debug connection.
Then, in your IDE, select the "Run -> Debug" window and create a new "Remote Java Application" configuration, passing the port set in MAVEN_OPTS (8787 in this case).
Once running this configuration in debug, the blocked Maven session will continue, enabling debugging from your IDE.
