Eclipse project import crashs

[Andreas Höhmann]

I'm trying to import latest version of swagger into eclipse for development ... but this fails wiith:

An internal error occurred during: "Importing Maven projects".
class org.eclipse.jdt.internal.core.JavaNature cannot be cast to class org.eclipse.jdt.core.IJavaProject (org.eclipse.jdt.internal.core.JavaNature and org.eclipse.jdt.core.IJavaProject are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @2e7de658)

Anyone here with the same?

I'm using eclipse:

Spring Tool Suite 4
Version: 4.22.0.RELEASE
Build Id: 202403071427
Revision: 44291b464093d161f115d8e16059e5272ed3c81d

Lombok v1.18.32 "Envious Ferret" is installed. https://projectlombok.org/

m2e: 2.6.0.20240220-1109

Hmmm ... maybe its my mistake?!

I configure now a jdk8 for the eclipse workspace (before this I have only a jdk17 defined) ... the eclipse itselfs runs with opendjk 22.

Now I can import the projects into eclipse but at the end I see everywhere:

Could not update project swagger-annotations-jakarta configuration
Path must include project and resource name: /

M2E Import doing some rounds ... now I have this final import state ... I'm not really sure if this is "okay". Any hint?

Specially these warnings not really clear to me:

Access "D:\Dev\git\privat\swagger-core" directory outside of project base directory. (org.apache.maven.plugins:maven-resources-plugin:3.1.0:resources:default-resources:process-resources)

And this error:

Failed to execute mojo org.apache.maven.plugins:maven-dependency-plugin:3.6.1:copy-dependencies {execution: copy-deps} (org.apache.maven.plugins:maven-dependency-plugin:3.6.1:copy-dependencies:copy-deps:package)

I found a temp. workaround!

I commented out the 2 extra resources in main pom.xml and swagger-project-jakarta pom.xml

<!--
            <resource>
                <targetPath>META-INF</targetPath>
                <directory>../..</directory>
                <filtering>true</filtering>
                <includes>
                    <include>NOTICE</include>
                    <include>LICENSE</include>
                </includes>
            </resource>
-->

Then the import into eclipse works fine. These relative path's are a problem (for eclipse / m2e).

I tried with:

                <directory>${project.basedir}/../..</directory>

Not working.

I think for a always working setup this resource must be defined only once in top-level pom and the directory must be an absolute path, which is not possible with pure maven. But there is a plugin for such things: https://github.com/jdcasey/directory-maven-plugin.
