Xiaobian to share with you how to use the exclusions tag in maven's pom.xml. I hope everyone has gained something after reading this article. Let's discuss it together!

Examples of maven pom.xml's exclusions tag in action projects org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-logging Explaining exclusion labels

This label is used to exclude the introduction of associative dependencies, because one of maven's pom dependencies is to introduce all associative dependencies.

What this tag does here is if the associated dependency might conflict with other introduced dependencies,

The associated dependencies must be excluded, so this label is used.

And this +s, you should know, can contain more than one!!!

Use exclusions to exclude dependencies

exclusions

But dependency regulation doesn't solve everything; we need exclusions to eliminate dependencies.

For example, if A is introduced into a project, A depends on B, but B is an older version.

At this point, you can use exclusions to exclude the transitive dependency and display the B dependency that declares an up-to-date version.

like this com.lowagie itext 4.2.1 bcmail-jdk14 bouncycastle bcprov-jdk14 bouncycastle bctsp-jdk14 bouncycastle

For example, if zookeeper is used, log4j conflicts are found.

We can also use this method to eliminate org.apache.zookeeper zookeeper 3.5.4-beta slf4j-log4j12 org.slf4j After reading this article, I believe you have a certain understanding of "how to use the exclusions tag in maven's pom.xml".
