Bundle 'org.jsoup' cannot be resolved

[agabaldon]

Did a pull today and built successfully on the command line. But in Eclipse, I can't make the jsoup error go away.

After starting Eclipse with an empty workspace and doing the following steps, I had no errors and 797 warnings in my Problems tab (note I had imported the projects before so they already had .project files):

1. Build the projects from the command line (mvn verify -DskipTests -Dtycho.localArtifacts=ignore)
2. Import the projects into the workspace as existing Maven projects
3. Open the project com.ge.research.sadl.target, open the file com.ge.research.sadl.target.target, and click "Set as Target Platform" in the upper right corner
4. The Problem tab will go from XXX errors YYY warnings to no errors 797 warnings
5. Open the file SadlMarkerDeserializerService.xtend and note there are no error markers on the "import org.jsoup.Jsoup" line

I had to additionally install the Xtend IDE from the Marketplace Client to get the same look as your screenshot since that software wasn't part of Eclipse Java originally, but there still were no errors even after restarting Eclipse and reopening the xtend file.

A clean install of Eclipse to 2021_03 and the SADL project worked. The question is what fixed it: upgrading Eclipse or reinstalling from scratch. I will try reinstalling 2020_12 and SADL from scratch when I have a chance.

Are there any upgrade requirements for Dev install or User (SADL plugin) install?

[tuxji]

SADL's target platform is Eclipse 2020-12. Dev installs (importing SADL projects into an Eclipse workspace) can succeed in both Eclipse 2020-12 and 2021-03. Even if the installed Eclipse platform is different than the target Eclipse platform, the errors will go away after you set the Eclipse workspace to the SADL projects' expected target platform. User installs (installing the SADL plugin into Eclipse) will succeed in Eclipse 2020-12 and may succeed in Eclipse 2021-03 as long as you don't have a conflicting Xtext SDK installed/required by other software. If you want to use Eclipse 2021-03, you're safer using Eclipse Java 2021-03 than Eclipse DSL 2021-03, which already has a newer Xtext SDK installed.

I suddenly got this error out of the clear blue, unclear why it suddenly appeared. I reloaded the platform, did a Maven update project on all projects, then ran a Maven clean followed by a Maven install and the problem disappeared.
