Gradle uses some unique script to manage the dependencies, which needs to be downloaded. Gradle will execute the tasks in the order that they are listed on the command-line, and will also execute the dependencies for each task. At Gradle, we often say that there are no optional dependencies: there are dependencies which are required if you use a specific feature. There are situation in modular approach when you want to exclude some of the dependency from that the library project used. We can have multiple transitive dependencies can be excluded by using the <exclusion> tag for each of the dependencies we want to exclude and placing all these exclusion tags inside the <exclusions> tag in pom.xml.

For example, the org.apache.commons:commons-lang3:3.8 module has an implicit capability with group org.apache.commons, name commons-lang3 and version 3.8.It is important to realize that capabilities are versioned. Flat Directory. The scenario can be like 1. So if there are multiple dependencies on a library, excludes are only exercised if all dependencies agree on them. About Mkyong.com. For example, the command gradle compile test will execute the compile and test tasks. Gradle script downloads the JAR and the dependency JAR when gradle script run. For such dependency how to exclude a particular library.. in this case the slf4j. Additionally, you can place custom tasks or binary plugins there if you have such. In a previous blog post, we demonstrated how capabilities could be used to elegantly solve the problem of having multiple logging frameworks on the classpath. Example: rootProject.name = 'mono-repo' // includes two sub-projects created respectively at: // * the ''api'' sub-directory // * the ''shared'' sub-directory include 'api', 'shared' // Changing .
