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()
}
This gradle config will produce myprogram-0.0.1.jar instead of myprogram-0.0.1-plain.jar
In your build.gradle.kts
// Build executable jar
tasks.jar {
enabled = true
// Remove `plain` postfix from jar file name
archiveClassifier.set("")
}
It was a change in Spring Boot 2.5.0.
As @ThomasKläger 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.
try use follow setting:
jar {
enabled = true
archiveClassifier = '' //use empty string
}
because org.springframework.boot.gradle.plugin.JavaPluginAction.java
private void classifyJarTask(Project project) {
project.getTasks().named(JavaPlugin.JAR_TASK_NAME, Jar.class)
.configure((task) -> task.getArchiveClassifier().convention("plain"));
}
from spring-boot-gradle-plugin sources file: https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-gradle-plugin/2.5.0/spring-boot-gradle-plugin-2.5.0-sources.jar
Instead of using the build gradle task you could use bootJar. That will only build the bootable jar.
Keep in mind that bootJar won't run your tests before building.
