Stuck on "5% Update project ..." for a long time

[abkieling]

After adding a new Maven dependency to pom.xml, a message saying "5% Update project ..." is shown in the status bar and takes a long time to complete. The plugin doesn't react quickly to dependency changes.

Environment

• Operating System: Fedora 30
• JDK version: 1.8
• Visual Studio Code version: 1.39.2
• Java extension version: 0.50.0

Steps To Reproduce

1. git clone git@github.com:apache/camel.git
2. Open components/camel-http project in VS Code
3. Open pom.xml
4. Add or remove a dependency

Current Result

The classes from the new dependency aren't available for a long time.

Expected Result

The classes from the new dependency should be available quickly.

Additional Informations

I don't think the long delay is due to downloading the new dependency. The same issue happens with already downloaded dependencies.

I can't reproduce the issue.
@alexkieling Could you provide a log - https://github.com/redhat-developer/vscode-java/wiki/Troubleshooting#enable-logging

[abkieling]

The logs don't show any error.

[snjeza]

Could you provide a project example?

[snjeza]

The logs don't show any error.

It isn't important. Could you attach it?

[abkieling]

I've updated the steps to reproduce the issue. It happens when working on an Apache Camel component.

[snjeza]

Apache Camel is a big project. It has 800+ maven modules. If you change root pom.xml, m2e (Java LS) updates all projects.
@alexkieling could you try to include only required folders/projects. See #1084 and eclipse-jdtls/eclipse.jdt.ls#1200

[abkieling]

I'm not opening the main project, just one of the component projects. Having said that, the component projects reference a components' parent pom. Maybe that's causing the issue?

[snjeza]

What project did you open?

[abkieling]

I'm working on a new component here but have tested changing the pom of an existing component (camel-http) and the same behavior was seen.

[snjeza]

@alexkieling Could you test test the issue using https://raw.githubusercontent.com/snjeza/vscode-test/master/java-0.52.0.vsix?

[abkieling]

The issue doesn't happen when using the version 0.52.0 you provided.

[snjeza]

@alexkieling Thanks.
The issue happens because Java LS forcibly updates Snapshots/Releases.

[fbricon]

A new java.maven.updateSnapshots preference was added, set to false by default. When set to true, it forces an update of Snapshots/Releases.

This issue is happening for me again in version 1.8.0. I imported another submodule and found that attempting to update the project would start a process that would freeze up at 5%. It has been like this for a long time. No logs to indicate the problem.
