Spring Boot 2 - Change Jar Name

Question

I am using Spring Boot 2 in my Gradle project to do a build to jar in Jenkins, and I would like to change the name of that jar file.

By default, Spring Boot 2 used the Gradle property rootProject.name, which can be set in the /settings.gradle file.

However, I would like to change the jar file name, without changing the rootProject.name.

Here are my bootJar and springBoot sections of the build.gradle file:

bootJar {   launchScript() } 

.

springBoot {   buildInfo {     properties {       artifact = "jarName"       group = "groupName"       name = "projectName"       version = "1.0"     }   } } 

Note: artifact is not setting the jar name, as I expected it to, after reading: https://docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/html/#integrating-with-actuator

Answer 1

archiveFileName is the new hotness. Everything else is deprecated.

bootJar {    archiveFileName = "${archiveBaseName.get()}.${archiveExtension.get()}" } 

or the Kotlin DSL equivalent:

tasks.getByName<org.springframework.boot.gradle.tasks.bundling.BootJar>("bootJar") {    this.archiveFileName.set("${archiveBaseName.get()}.${archiveExtension.get()}") } 

See:

• https://docs.gradle.org/current/dsl/org.gradle.api.tasks.bundling.Jar.html#org.gradle.api.tasks.bundling.Jar:archiveName

• https://docs.gradle.org/current/userguide/lazy_configuration.html

Answer 2

Since bootJar tasks extends Jar you can use archiveName to set name the directly:

bootJar {    archiveName = 'whatever' } 

Have a look here.
