To do that, let’s create an Application class with a main() method. We can see that the default executions are disabled using phase none, and Java-specific executions are bound to compile and test-compile phases. We need to disable them and enable java-compile and java-test-compile instead to ensure that kotlin-maven-plugin execution will happen before maven-compiler-plugin: But the former has two specific executions that are executed before everything else during the phases: default-compile and default-testCompile. So we should place maven-compiler-plugin after kotlin-maven-plugin. We need to adapt maven-compiler-plugin configuration as we need Kotlin sources to be compiled before Java sources.įrequently, Maven plugins executions happen according to the declaration order. It is developed under the Apache 2. Kotlin is free, has been free and will remain free. This is nearly the end of the configuration. Kotlin is a programming language introduced by JetBrains in 2011, the official designer of the most intelligent Java IDE, named Intellij IDEA.
