需要帮助构建一个可执行jar(可以使用java -jar app.jar运行(，该jar可以发布到maven本地repo(使用gradle publishToMavenLocal(，用于春季启动项目。
通过这些渐变设置，gradle publishToMavenLocal起作用。

但是使用这些渐变设置构建的罐子在尝试运行时会破裂

我已经尝试了这里建议的变通方法(https://docs.gradle.org/current/userguide/upgrading_version_6.html#publishing_spring_boot_applications)用于发布CCD_ 6工件。罐子在这种情况下工作得很好，但是，
configurations {
listOf(apiElements, runtimeElements).forEach {
it.get().outgoing.artifacts.removeIf { it.buildDependencies.getDependencies(null).contains(tasks.jar) }
it.get().outgoing.artifact(tasks.bootJar)
}
}
但gradle不允许我进行gradle pTML
➜ example-user git:(master) ✗ gradle pTML
> Task :user-service:publishMavenJavaPublicationToMavenLocal FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':user-service:publishMavenJavaPublicationToMavenLocal'.
> Failed to publish publication 'mavenJava' to repository 'mavenLocal'
> Artifact example-service-0.0.1-SNAPSHOT.jar wasn't produced by this build.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at https://help.gradle.org
BUILD FAILED in 1s
16 actionable tasks: 3 executed, 13 up-to-date
解决了需要在发布范围中定义artifact的问题。
publishing {
publications {
create<MavenPublication>("mavenJava") {
//from(components["java"]) // <-- this is not required
artifact(tasks.bootJar.get()) // <-- this is required
}
}
}
和轻微修改的configurations范围(参考(：
configurations {
listOf(apiElements, runtimeElements).forEach {
// Method #1
val jar by tasks
it.get().outgoing.artifacts.removeIf { it.buildDependencies.getDependencies(null).contains(jar) }
// Method #2
it.get().outgoing.artifact(tasks.bootJar)
}
}
以下是发布出版物的一些示例实现。
我修复了将参数enabled = true添加到jar任务的错误Artifact ....jar wasn't produced by this build
jar {
enabled = true
}
