I have tried to import the langchaing4j project in Eclipse/VS Code/Cursor and faced the following issues:

1. m2e sets JRE 1.8 instead of JRE 17 - https://github.com/langchain4j/langchain4j/blob/a06ec71840a7f28dec2882369599115a832f7817/langchain4j-parent/pom.xml#L39
   This issue doesn’t happen in VS Code and Cursor because they use an older m2e version.

2. m2e doesn’t add ../langchain4j-test/src/main/java to the source folders of the langchain4j-core project - https://github.com/langchain4j/langchain4j/blob/a06ec71840a7f28dec2882369599115a832f7817/langchain4j-core/pom.xml#L104
