Developing DBeaver with IntelliJ IDEA

[EastLord]

Hi everyone,

According to the official wiki guide, I’ve successfully set up and run DBeaver locally using IntelliJ IDEA.

However, I have a question: after I make code changes in IDEA, I find that I need to manually compile the affected module using the mvn command in the terminal and then restart the application for the changes to take effect.

Is there a more efficient way to apply changes (especially UI-related or plugin-related ones) directly from IDEA without rebuilding via the command line every time? For example, can I use IntelliJ's internal build system or hot reload techniques to speed up the dev-test cycle?

Any suggestions or best practices are appreciated. Thanks!

Weird, what happens when you compile using IDEA?

[EastLord]

Sorry, I might not have expressed my point clearly. Actually, I can compile using IDEA by going to the Build -> Build Project option in the status bar, but this requires manual action. If I modify the code and then directly click the Debug or Run button in the top right, the changes don’t take effect because the code hasn't been compiled.

@EastLord, you can make it do that by adding the following options. After that, I would recommend moving the launch configuration from the Generated folder to avoid it being rewritten.

Thank you very much for your help. I believe this meets my needs.

@EastLord how did you managed to run it in the first place? Because the wiki does not specify what to choose for the launch/debug configuration, there is no preset file (runConfiguration) and you can't even guess it by the last screenshot which is cropped.

I always get "java.io.FileNotFoundException: Could not find framework under /home/sam/development/dbeaver-INTELLIJ/dbeaver/plugins/org.jkiss.dbeaver.launcher/target/classes/plugins" with these settings:

This means two thing:

• i need better glasses 😄 ("It should contain all launch configurations.")
• Something might have gone wrong in the generate_workspace script
  However, while it was running it saw no errors, and it seemly ended with a "nice" message. At first glance it does not seem to store a a log file of the script output. I'll run again with | tee -a to have a file to double-check for runtime errors.

Now that i re-generated the workspace, the generate-workspace.sh script had one error during it's execution:

14:43:27 [ERROR] c.d.o.d.p.resolvers.PluginResolver - Couldn't find plugin 'org.eclipse.ecf.provider.filetransfer.httpclient5.win32=null'
and fails with:

14:45:32 [INFO ] o.j.tools.rcplaunchconfig.EntryPoint - Producing final IML configuration... java.lang.NullPointerException: Cannot invoke "java.util.Map.get(Object)" because "this.runBeforeConfigs" is null at com.dbeaver.osgi.dependency.processing.PathsManager.getRunBeforeConfigs(PathsManager.java:356) at org.jkiss.tools.rcplaunchconfig.producers.iml.IMLConfigurationProducer.generateLaunchConfig(IMLConfigurationProducer.java:237) at org.jkiss.tools.rcplaunchconfig.producers.iml.IMLConfigurationProducer.createRunConfiguration(IMLConfigurationProducer.java:181) at org.jkiss.tools.rcplaunchconfig.producers.iml.IMLConfigurationProducer.generateImplConfiguration(IMLConfigurationProducer.java:143) at org.jkiss.tools.rcplaunchconfig.EntryPoint.launchGenerate(EntryPoint.java:220) at org.jkiss.tools.rcplaunchconfig.EntryPoint.main(EntryPoint.java:61) at org.codehaus.mojo.exec.ExecJavaMojo$1.run(ExecJavaMojo.java:279) at java.base/java.lang.Thread.run(Thread.java:1474)

i think something is failing here (inside /dbeaver-osgi-common/osgi.dependency.processing/src/main/java/com/dbeaver/osgi/dependency/processing/PathsManager.java):
runBeforeConfigs = Arrays.stream(runBeforeScriptsString.split(";")) .map(String::trim) .map(s -> s.split("=")) .filter(arr -> arr.length == 2) .collect(Collectors.toMap(arr -> arr[0], arr -> Set.of(arr[1].split(","))));

Because runBeforeScriptsString takes the value of a constant.
What could i do? Should i modify this java class to have more details while running the script?

Hi, thanks for the report, going to fix that soon.

[Destrolaric]

@samuele555 Should be fixed now in the recent devel

[samuele555]

I deleted the generated workspace, updated all repositories with fresh code, re-run generate_workspace.sh and finally my run configurations where correctly set and i managed to finally run the project and got dbeaver application to open 😄
