Spring Boot 2.5.0 generates plain.jar file. Can I remove it?


After the Spring Boot 2.5.0 update, it generates the myprogram-0.0.1-plain.jar file alongside the usual myprogram-0.0.1.jar. Can I disallow gradle to generate the *.plain.jar file? I use Gradle 7.0.2.

What I get:

build/
  libs/
    myprogram-0.0.1.jar
    myprogram-0.0.1-plain.jar

What I want:

build/
  libs/
    myprogram-0.0.1.jar

build.gradle:

plugins {
    id 'org.springframework.boot' version '2.5.0'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}


Solution

  • It was a change in Spring Boot 2.5.0.

    As @ThomasKl├Ąger pointed out: You can set it in the build.gradle configuration.

    build.gradle

    jar {
        enabled = false
    }
    

    For Kotlin devs:

    tasks.getByName<Jar>("jar") {
        enabled = false
    }
    

    Alternatively, you can run the bootJar task. It produces only the default runnable jar.
