How to resolve the Maven Jar bundle Dependency version conflict (Dependency collision)

Because many jar packages are interdependent, it is easy to generate versioning problems when using MAVEN to build a project.

Problem: Compile compilation passed, but test tests or install after the program error

Tip method is not found, by looking at the class that throws the exception, you can see that the referenced class does not have this method, because when it is run, a different version of the jar package is referenced.

Workaround:

Step 1: Open Pom.xml through MyEclipse, open dependency hierarchy, find the corresponding package for the error class

It was found that some relied on beans 3.2.0 and some relied on beans 3.2.8.

Step 2: Right button > Exclude Maven artifact
