Need help with dependency resolution on NBM

[charly4711]

Hi,
so, when I try to load a given module into my running IDE, I keep getting:

INFO [org.netbeans.modules.maven.apisupport.ExecutionChecker]: Error reloading netbeans module in development IDE.
java.io.IOException: Cannot enable StandardModule:net.jarre_de_the.MavenRemoteSearch jarFile: /Users/khb/Sources/MavenRemoteSearch/target/nbm/clusters/extra/modules/net-jarre_de_the-MavenRemoteSearch.jar; problems: [module org.netbeans.api.annotations.common/1 > 1.59, module com.squareup.okhttp3 > 5.3.2]

What totally baffles me is that I'm working in NB16 and all my dependencies are towards NB16 or RELEASE160.
After adding a direct dependency in my POM, the maven task even added a dependency in the manifest to the version that IS the version of the module in NB160 (1.46):

OpenIDE-Module-Module-Dependencies: org.netbeans.modules.maven/2 = 1, or
 g.netbeans.modules.maven.indexer/2 = 16-321935444b183aea1c4ff255d8d2ab8
 d50c60606, org.openide.modules > 7.66, org.netbeans.api.annotations.com
 mon/1 > 1.46, org.openide.util > 9.26, org.netbeans.api.progress/1 > 1.
 66

Nowhere in my code do I even have the number 59 anywhere and surely NB16 couldn't even know if I was referring to something in the annotations api that required a more recent version?!?

Also, what's wrong with okhttp3 when it is in here:

Class-Path: ext/net.jarre_de_the.MavenRemoteSearch/com-squareup-okhttp3/
 okhttp-jvm.jar ext/net.jarre_de_the.MavenRemoteSearch/com-squareup-okio
 /okio-jvm.jar ext/net.jarre_de_the.MavenRemoteSearch/org-jetbrains-kotl
 in/kotlin-stdlib.jar ext/net.jarre_de_the.MavenRemoteSearch/org-jetbrai
 ns/annotations.jar ext/net.jarre_de_the.MavenRemoteSearch/com-squareup-
 okio/okio.jar

and also in the actual nbm:

        0  05-31-2026 19:03   netbeans/modules/ext/net.jarre_de_the.MavenRemoteSearch/
        0  05-31-2026 19:03   netbeans/modules/ext/net.jarre_de_the.MavenRemoteSearch/com-squareup-okhttp3/
   868403  05-31-2026 19:03   netbeans/modules/ext/net.jarre_de_the.MavenRemoteSearch/com-squareup-okhttp3/okhttp-jvm.jar

Any tips to unfry my brain would be appreciated.
TIA,
C.

It would be helpful to see this in context - i.e. where is the source code?

Thanks for the reply.
I wasn't ready to share the code, yet, esp. because in my POC environment I had copied and refactored stuff over without giving proper credit to the original author etc.
So, I went and cleaned it all up, did a proper fork etc. etc. ... and you know what? I can now deploy the module. It looks like my issues were a combination of clearing out some leftovers of earlier stages of the module, realizing one of my the dependencies I had upgraded was now using OSGi and apparently I have no idea how to make that work so I reverted to the version the original code used, adding two more dependencies for code analysis stuff maven does .... and lo and behold ...

Unfortunately, now the code doesn't seem to do anything. I cannot get it to trigger in a debug session.

This module is supposed to allow one to search maven repos online (if I'm getting the code correctly, from quick search) so you could potentially disable indexing of maven repos. The other day my maven index was 12 GB and I felt it might be worth doing that. On the other hand, while testing the module, I removed my maven index and later recreated it ... it is now 1GB, sooooooo.

So, while I kinda wonder if the following maybe just doesn't work that way anymore (and being unable to find Maven-Indexer at https://bits.netbeans.org/dev/javadoc/ ... probably because it's not actually an API)

@ServiceProvider(service = RepositoryIndexQueryProvider.class, position = 100)
public class MavenCentralOnlineRepositoryIndexQueryProvider implements RepositoryIndexQueryProvider {

... the urgency is kinda gone.

Don't use implementation dependencies. They are evil and will break and in this case it does to. Change the project like this:

# This patch file was generated by NetBeans IDE
# It uses platform neutral UTF-8 encoding and \n newlines.

Changes:

• maven indexer allows the module with codename base ro.emilianbold.modules.maven.search.remote to use friend API, so for now lets reuse that instead of an implementation dependency (long term either this function must move into the NetBeans codebase or maven indexer needs a real API)
• drop the implementation dependencies
• use current version of maven-compiler-plugin, use release flag, enable annotation processing (relevant on newer JDKs, which by default don't run annotation processors found on the classpath unless instructured)
• remove unused maven dependency

Cool, this actually does work!
I was just wrong, guessing how to use it. It does not use Quick Search but (obviously more importantly) searching Maven repos from the Services tab or when adding a dependencies. There are some caveats like no support for mirrors (probably because there's no good way of knowing if any given mirror would support the same kind of query URLs), you need to check the name field when searching from the Services tab (because otherwise the code will try to find your search term in group-id, artifact-id AND version, probably because of the way the add dependency stuff works), which I added to the README.
