Unable to import HAPI-FHIR in Eclipse

[David Otasek]

Myself and one other developer have been unable to import HAPI-FHIR into Eclipse using the steps in the HAPI-FHIR hacking guide:

https://hapifhir.io/hapi-fhir/docs/contributing/hacking_guide.html

I have tried with Eclipse 2021-09 and 2022-06.

In both cases, the following plugins were installed:

• lombok-1.18.24
• Kotlin Plugin for Eclipse 0.8.22

I also installed the recommended m2e connectors, and ignored one build step that Eclipse appears unable to handle:

The import reports failures once it is done, and gives a 100+ long list of various errors.


Selecting 'Maven -> Update Project' on hapi-fhir and updating dependencies on all the projects doesn't help. 

The only mild improvement I get on building modules is switching Java to 17 in the build path (see below, where the default is still 11, which refuses to build).



'mvn clean install -DskipTests' works on the command line. Importing into IntellliJ IDEA appears to work fine as well. However, there doesn't appear to be a clean way for those used to working in Eclipse to contribute.

Note: Switching to Java 17 in the Java build path would have to be done individually per project, so feels like a bad solution. If there's a clean way to do this automatically, I can try it, and see if it gets me any further.

Hi David

Not sure if it helps much, but I have an eclipse setup working with hapi-fhir with

2020-03 (Eclipse Java Development Tools Version: 3.18.300.v20200305-0155).

I noticed when installing a new version that it did not work, so I continued working

in the old version ...

Best regards

Oliver

Helllo David, 

Have you tried to do troubleshooting mentioned in the guide?

Thanks.

Thanks for the feedback;

Dropping down to older versions isn't something I can endorse. Good to know it worked at some point in Eclipse's history; thanks Oliver!

> Have you tried to do troubleshooting mentioned in the guide?

I have. I started with fresh git clone's of the project each time, and even blasted away all the eclipse generated files and tried re-importing:

find . -name ".classpath" -delete

find . -name ".project" -delete

find . -name ".settings" -exec rm -rf {} +

None of this made a difference.

Interesting .. Have you raised the issue in the git ?

That might be a quickest way to be fixed or looked into. Also, i am curious to reproduce the error although I would use idea intellij.

Thanks.
