在Netbeans / Maven中远程调试单元测试

Question

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."

Answer 1

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.)

• 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

• Create new mvn script.

   #!/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 

• 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 .

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

  • 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> 

    

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

  • I'm still looking for a way to set up this configuration globally. If you know how to do this, please tell me!
• Alternatively, create a Custom Action that has the same properties set.
• I should mention that the debug experience works pretty well, thanks to the remote debug capabilities built into the JVM and the version/dependency tracking of Maven and the excellent Maven integration in Netbeans. I really like that you're able to easily step into the code of other projects (and it can resolve specific versions).
