JUnit5 Gradle插件会覆盖默认的构建任务

Question

I'm using the JUnit 5 Gradle plugin as explained here: http://junit.org/junit5/docs/current/user-guide/#running-tests-build-gradle

I added the following parts to my gradle.build file:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.3'
    }
}

plugins {
    id 'java'
    id 'application'
    // ... some others...
}

apply plugin: 'org.junit.platform.gradle.plugin'

dependencies {
    testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-api', version: '5.0.3'
    testRuntime group: 'org.junit.jupiter', name: 'junit-jupiter-engine', version: '5.0.3'
}

With the above, when I use the gradle build task - I have the following output:

Executing task 'build'...

:compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:jar
:findMainClass
:startScripts UP-TO-DATE
:distTar
:distZip
:bootRepackage
:assemble
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:junitPlatformTest UP-TO-DATE
:test SKIPPED
:check UP-TO-DATE
:build

BUILD SUCCESSFUL

Since this includes junitPlatformTest I assume that the plugin overrides the regular build task. I would like to know if there's any way to avoid this behavior.

Answer 1

The plugin does not override the build task. It adds a dependency from the test task to the junitPlatformTest task and (by default) disables the standard test task (to avoid executing JUnit 4-based tests multiple times).

build depends on check and assemble , check depends on test (see Gradle User Manual ). Thus, when you execute build , junitPlatformTest will be executed as in your example.
