IDEA - Gradle - Gretty - Tomcat 调试

build.gradle

gretty {
    port = 8081
    servletContainer = 'tomcat8'
    contextPath = '/'
    afterEvaluate {
        appStartDebug {//修改debug时的监听端口，默认使用5005端口
            debugPort = 9999   //此处填写端口号，如8080,如果修改端口号，则IDEA中的Remote 调试工具中需要填写相同的端口
            debugSuspend = true
        }
    }
}
