Unable to see the highlight in the editor section for the Java debugging #14576

ghost · 2019-09-17T16:28:45Z

Running che 7.1.0 with che-java11-maven, set few breakpoints and start debugging. Unable to see the highlight on the line where the breakpoint is set (shown in the attached image). Any suggestion?

l0rd · 2019-09-17T19:51:28Z

@rbcminghou I am not able to reproduce it. What browser are you using?

ghost · 2019-09-17T19:52:57Z

Chrome

l0rd · 2019-09-17T19:59:12Z

@rbcminghou I have no clue why this is happening. @tsmaeder @tolusha ?

ghost · 2019-09-17T20:13:17Z

Attached the images for my plugins and editors:

I am running Java 11 with the following container images:
eclipse/che-java11-maven:7.1.0
eclipse/che-machine-exec:7.1.0
eclipse/che-theia:7.1.0
eclipse/che-remote-plugin-runner-java11:next

Is there something I can look up my log?

tolusha · 2019-09-18T07:10:54Z

@rbcminghou
Could you provide a github link to your app?

Is there something I can look up my log?

Preferences -> Debug -> trace (set to true).
Then open output view for Debug Adapters to check detailed logs

ghost · 2019-09-18T14:14:29Z

@tolusha, sorry I do not have the github link for my app.

Just copied and pasted all logs from "Debug Adapters":

update for my app github link: https://github.com/rbcminghou/java-maven-helloworld

tolusha · 2019-09-24T06:50:30Z

@rbcminghou
Could you also provide debug configuration and command to start application in debug mode?

ghost · 2019-09-24T11:12:35Z

The debug command:

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000 -cp ./target/*.jar com.rbccm.app.Helloworld

The debug configuration (launch.json):

{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
"version": "0.2.0",
"configurations": [
{
"type": "java",
"name": "Debug (Attach)",
"request": "attach",
"hostName": "localhost",
"port": 8000
}
]
}

amisevsk · 2019-09-24T15:20:34Z

The above, formatted for readability:

The debug command:

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000 -cp ./target/*.jar com.rbccm.app.Helloworld

The debug configuration (launch.json):

{
  "version": "0.2.0",
  "configurations": [
    {
        "type": "java",
        "name": "Debug (Attach)",
        "request": "attach",
        "hostName": "localhost",
        "port": 8000
    }
  ]
}

To add to the discussion, I've encountered this once before but did not have a chance to debug the issue (was during a demo). In my case, the environment was minishift + Che 7.1.0.

ghost · 2019-09-24T19:16:16Z

Thanks for the comments and my environment is OCP 3.11 + che 7.1.0.

amisevsk · 2019-09-24T20:34:46Z

I've restarted a minishift a few times since this originally occurred for me, but I currently can't reproduce it.

tolusha · 2019-09-25T06:21:06Z

I can't reproduce it either. (

ghost · 2019-09-25T14:57:20Z

Do I need to need the addition plugins or special configuration? Since my environment and setup are default but behind the firewall (all docker images have to be pulled and pushed into my private registry prior to exdecute chectl server:start).

amisevsk · 2019-09-25T16:43:17Z

AFAIK debugging in Theia should work (and does work in your case, it just doesn't show the line highlight). I'm at a loss as to what the issue is, though, until I can reproduce it again.

amisevsk · 2019-09-25T17:47:04Z

Setting label area/che-theia since it looks like the highlight div and margin icon are not being updated when the breakpoint is hit.

From what I can tell, the line highlight should come from a div with class cdr theia-debug-top-stack-frame-line; I suspect the DOM is not getting updated to include it.

ghost · 2019-09-26T16:31:42Z

I just tried the debugging on my Windows chrome and the same result on my MacOS chrome with missing highlight.

tsmaeder · 2019-09-27T07:33:51Z

@rbcminghou maybe sharing your devfile might help.

I don't think it's a devfile-specific issue, since I had it occur once when running a known-working devfile.

updated to 7.2.0 and the issue is still there...

amisevsk · 2019-10-08T15:57:40Z

I have been unable to reproduce on any of my deployments since the one time it happened for me. I'm at a loss on this issue.

If I type the Java code in the editor directly, and it works fine:

And, I realized there is the title option "Run|Debug".

But, the first screenshot at the begin message was imported from github and it does not have "Run|Debug" on the top of my main function. How do I enable it?

@rbcminghou that would indicate that the project is not recognized as a java project by the java language server. Does refreshing the browser help? Otherwise, try the "clean the java language server workspace" command.

No help after refreshing my chrome browser.

The "clean the java language server workspace" command works once to get "Run|Debug".

Delete the workspace and get the project back from github, then try the "clean the java language server workspace" command, "Run|Debug" does not shown again.

Update:
My environment is behind the firewall and need the proxy setup. Therefore, I copy the settings.xml to /home/users/.m2 and execute the "clean the java language server workspace" command. The "Run|Debug" shows up.

will JLS will check the pom.xml and ensure dependencies are okay?
can we use devfile to copy settings.xml to /home/users/.m2 when the workspace is starting up?

Yes, jdt.ls does not pick up new projects after it has been initialized: eclipse-jdtls/eclipse.jdt.ls#901
Doing a browser refresh should restart the language server, though.

ghost · 2019-10-11T13:37:18Z

yes, the refresh browser works now after copying settings.xml (contain the proxy settings) to /home/user/.m2

Issues go stale after 180 days of inactivity. lifecycle/stale issues rot after an additional 7 days of inactivity and eventually close.

Mark the issue as fresh with /remove-lifecycle stale in a new comment.

If this issue is safe to close now please do so.

Moderators: Add lifecycle/frozen label to avoid stale mode.
