IntelliJ IDEA requires modules for langchain4j

[InAnYan]

JabRef version

5.13 (latest release)

Operating system

Windows

Details on version and operating system

Windows 11

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

Just write the code with langchain4j library.

Appendix

The error IntelliJ gives is:

Package 'dev.langchain4j.data.message' is declared in module 'langchain4j.core', but module 'org.jabref' does not read it

The same applies for other classes.

However, the code compiles without any errors.

Moreover, if we apply the IDEA's advice, the building breaks.

@koppor In the repository intellij-issue-modularity I made all the changes, but it stuck at error:

D:\Git\intellij-issue-modularity\src\main\java\org\example\Main.java:5: error: cannot find symbol
import dev.langchain4j.model.embedding.AllMiniLmL6V2EmbeddingModel;
                                      ^
  symbol:   class AllMiniLmL6V2EmbeddingModel
  location: package dev.langchain4j.model.embedding

Could you please update the repo with the changes you made in JabRef?

[koppor]

Can't we add --patch-module (based on the contents of build.gradle) similar to the other "Compilation options" given at https://devdocs.jabref.org/getting-into-the-code/guidelines-for-setting-up-a-local-workspace/intellij-12-build.html.

Done. See InAnYan/intellij-issue-modularity@7ba30fa.

[koppor]

BTW, there is a work-around:

Please add following things to intellij-12-build.md (rendered at https://devdocs.jabref.org/getting-into-the-code/guidelines-for-setting-up-a-local-workspace/intellij-12-build.html)

--add-reads
org.example=langchain4j.embeddings.all.minilm.l6.v2
--add-reads org.example=langchain4j.core

In the text box where other paramters to JabRef.main module are added:

[InAnYan]

New parameters:

--add-exports=javafx.controls/com.sun.javafx.scene.control=org.jabref
--add-exports=org.controlsfx.controls/impl.org.controlsfx.skin=org.jabref
--add-reads
org.jabref=org.fxmisc.flowless
--add-reads
org.jabref=org.apache.commons.csv
--add-reads
org.jabref=langchain4j.embeddings.all.minilm.l6.v2
--add-reads
org.jabref=langchain4j.embeddings.all.minilm.l6.v2.q
--add-reads
org.jabref=langchain4j.core
--add-reads
org.jabref=langchain4j.open.ai

With the fix, there are no compiler errors, the imports are without errors, too:

Thus, closing this issue.

[koppor]

Reopening; cannot get --patch-module to work. I always get

---

Blocked by langchain4j/langchain4j#1066

[koppor]

@InAnYan This can be closed, because with the configuration of the compiler, the issue indicated by the title is working

@InAnYan I would propose to open another issue for compilation with IntelliJ referencing to langchain4j/langchain4j#1066. This is different enough to this one.
