我很难从我的 Gradle 应用程序创建一个胖罐子。
我正在运行命令./gradlew jar
和./gradlew clean build
. 这两个命令似乎都.jars
在应用程序的各个子模块中创建有效,但.jar
项目根目录中的 仅包含MANIFEST.MF
并且没有其他内容。
该应用程序的结构如下所示
nova-app
; 这是main
方法所在的项目和Dropwizard的config.yml
文件nova-dal
nova-core
build.gradle
Procfile
settings.gradle
- ... 其他不相关的文件/文件夹
build.gradle(在根项目中)
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
import java.net.URI
plugins {
base
kotlin("jvm") version "1.3.72"
`maven-publish`
// Apply the application plugin to add support for building a CLI application.
java
application
}
application {
mainClassName = "com.nova.app.Nova"
}
tasks.withType<Jar> {
enabled = true
manifest {
attributes["Main-Class"] = application.mainClassName
}
from(configurations.runtimeClasspath.get().map {if (it.isDirectory) it else zipTree(it)})
}
allprojects {
group = "com.nova"
version = "1.0.0"
repositories {
mavenCentral()
maven { url = URI("https://plugins.gradle.org/m2/") }
}
tasks.withType<KotlinCompile>().configureEach {
kotlinOptions.jvmTarget = "1.8"
kotlinOptions.javaParameters = true
}
}
tasks.register("stage") {
dependsOn(":clean", ":build")
}
subprojects {
apply(plugin = "kotlin")
apply(plugin = "jacoco")
apply(plugin = "maven-publish")
tasks.withType<Test>().configureEach {
useJUnitPlatform()
}
dependencies {
...
}
configurations.all {
resolutionStrategy.preferProjectModules()
}
repositories {
mavenLocal()
mavenCentral()
jcenter()
}
}
build.gradle(在nova-app
主类所在的项目中)
import org.springframework.boot.gradle.tasks.bundling.BootJar
plugins {
id("org.springframework.boot") version "2.1.3.RELEASE"
}
tasks.withType<Jar> {
enabled = true
}
tasks.withType<BootJar> {
archiveFileName.set("${this.archiveBaseName.get()}.${this.archiveExtension.get()}")
}
dependencies {
"implementation"(project(":nova-core"))
"implementation"(project(":nova-dal"))
}
设置.gradle
rootProject.name = 'nova'
include ':nova-app'
include ':nova-core'
include ':nova-dal'
我希望能够使用类似的命令运行应用程序java -jar build/libs/nova-1.0.0.jar
,但目前我得到了Caused by: java.lang.ClassNotFoundException: com.nova.app.Nova
有人可以指出这个设置有什么问题吗?
