Maven dependency resolution guide: advanced patterns with transitive dependencies in a React project
I'm testing a new approach and Hey everyone, I'm running into an issue that's driving me crazy..... I've looked through the documentation and I'm still confused about I'm currently working with a frustrating scenario while trying to manage dependencies in my Maven project that integrates with a React frontend. My backend is a Spring Boot application using Maven 3.8.4, and I have several dependencies that are supposed to be included transitively. However, when I run `mvn clean install`, I notice that some transitive dependencies are not being resolved correctly. For instance, I'm using the following in my `pom.xml`: ```xml <dependency> <groupId>com.example</groupId> <artifactId>my-backend-lib</artifactId> <version>1.0.0</version> </dependency> ``` The `my-backend-lib` library has its own dependencies, including `commons-lang3` and `log4j`, which are supposed to be included. However, when I check my target directory after building, I see that `commons-lang3` is missing, and I get the following behavior during runtime: ``` java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils ``` I've tried running `mvn dependency:tree` to troubleshoot the dependency hierarchy, and it's showing that `commons-lang3` is indeed a transitive dependency of `my-backend-lib`: ``` [INFO] +- com.example:my-backend-lib:jar:1.0.0:compile [INFO] | +- org.apache.commons:commons-lang3:jar:3.12.0:compile ``` Yet it doesn't appear in the `target` folder. I've checked for any exclusions in the `my-backend-lib` library's `pom.xml`, but nothing stands out. Additionally, I've tried adding the `commons-lang3` dependency explicitly: ```xml <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.12.0</version> </dependency> ``` This works, but I feel like it defeats the purpose of having transitive dependencies. Can anyone guide to understand why this is happening? Is there a configuration I might be missing, or a best practice that could solve this scenario? Any ideas what could be causing this? I'm using Java LTS in this project. Thanks for taking the time to read this! The stack includes Java and several other technologies. Is there a better approach?
