在Netbeans / Maven中远程调试单元测试 [英] Remotely debug unit tests in Netbeans / Maven

问题描述

我想使用Netbeans在Maven项目中的远程计算机上自动启动和调试单元测试。所有IDE功能都应该可以工作，例如调试，输出窗口等。只需单击调试聚焦测试方法，该过程就必须完全自动化。

I would like to automatically launch and debug unit tests on a remote machine in a Maven project using Netbeans. All the IDE features should work, such as debugging, the output window, etc. The process has to be fully automated with a single click of "Debug Focused Test Method."

推荐答案

解决方案是用自定义脚本替换 mvn 命令，该脚本将执行 rsync 和 ssh 。通过这两种工具的神奇之处，它可以很好地实现 。此外，它应该可以移植到其他Maven IDE。当前指南适用于 bash ，但同样的想法可以在Windows中使用 powershell 实现， groovy ，甚至 cmd 。 （我尝试使用Nashorn，但是在正确保留所有参数的同时执行其他命令的方式似乎已经破解。）

The solution is to replace the mvn command with a custom script which will perform an rsync and an ssh. Through the magic of both tools, it works really well. Also, it should be portable to other Maven IDEs. The current guide is for bash, but the same idea could be implemented in Windows with powershell, groovy, or even cmd. (I tried to use Nashorn, but the way to execute other commands while properly preserving all the arguments seemed broken.)

• 在Netbeans目录中 /usr/local/netbeans-8.1/java/maven/bin / ，重命名 mvn 脚本：
  
  
  
  
  • cd /usr/local/netbeans-8.1/java/maven/bin /
  
  
  • sudo mv mvn mvn.orig
  
  
  • In Netbeans directory /usr/local/netbeans-8.1/java/maven/bin/, rename the mvn script:
    • cd /usr/local/netbeans-8.1/java/maven/bin/
    • sudo mv mvn mvn.orig

    创建新 mvn 脚本。

    #!/bin/bash
    
    if [ -z "$REMOTE" ] ; then 
        SCRIPTDIR=$(dirname "$0")
        "$SCRIPTDIR/mvn.orig" "$@"
    else
        if [ -z "$REMOTE_BASE_DIR" ] ; then
            echo "ERROR: Please set environment variable REMOTE_BASE_DIR to the folder which contains the project directory"
            exit
        fi
    
        PROJECT_DIR=$(basename "$(pwd)")
        REMOTE_PROJECT_DIR=$REMOTE_BASE_DIR/$PROJECT_DIR/
        ARGS=
        for var in "$@"
        do
         ARGS="$ARGS \\\"$var\\\""
        done
    
        echo "Syncing project directory..."
        (set -x; rsync -aczhW --progress --delete --exclude '.git' --exclude 'target' $RSYNC_OPTS ./ "$REMOTE:\"$REMOTE_PROJECT_DIR\"")
    
        echo "Executing maven..."
        if [ "$REMOTE_PORT" = '${jpda.address}' ] ; then
            (set -x; ssh ${REMOTE} "cd \"$REMOTE_PROJECT_DIR\"; mvn $ARGS")
        else
            (set -x; ssh -R $REMOTE_PORT:localhost:$REMOTE_PORT ${REMOTE} "cd \"$REMOTE_PROJECT_DIR\"; mvn $ARGS")
        fi
    fi
    

  
  
  • 配置远程机器：
    
    
    
    
    • 安装 mvn ，或安装Netbeans并将其 mvn 放在路径上。我选择了后者，但要么应该没问题。
    
    
    • 配置ssh。我不会在这里描述如何做到这一点。确保 AllowTcpForwarding 设置为是或远程 in / etc / ssh / sshd_config 。
    
    
    • Configure the remote machine:
      • Either install mvn, or install Netbeans and put its mvn on the path. I chose the later, but either should be fine.
      • Configure ssh. I won't describe how to do it here. Make sure that AllowTcpForwarding is set to yes or remote in /etc/ssh/sshd_config.

      创建新的Netbeans配置将所有maven操作（包括clean& build）转发到远程计算机：

      Create new Netbeans configuration that will forward all maven actions (including clean & build) to the remote machine:

      
      
      • 进入项目属性
      
      
      • 创建新配置
      
      

      • 在设置属性中添加：

      • Go into Project's properties
      • Create new Configuration

      • In "Set properties" add:

      Env.REMOTE_BASE_DIR=<directory on the server that will contain your project directory>
      Env.REMOTE=<address of remote machine>
      Env.REMOTE_PORT=${jpda.address}
      Env.RSYNC_OPTS=<optional, but could be another --exclude>
      

      要使用，请在工具栏的下拉菜单中选择新配置，并照常调用任何maven目标。

      To use, select the new configuration in the drop-down menu in the toolbar, and invoke any maven goal as usual.
