我很难用Gradle应用程序创建胖子。
我正在运行命令./gradlew jar
和./gradlew clean build
。这两个命令似乎都在应用程序的各个子模块中创建了有效的.jars
,但是项目根目录中的.jar
仅包含MANIFEST.MF
,没有其他内容。
应用程序的结构如下
-
nova-app
;这是main
方法所在的项目,也是Dropwizard的config.yml
文件所在的项目 -
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 (在主类所在的nova-app
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"))
}
settings.gradle
rootProject.name = 'nova'
include ':nova-app'
include ':nova-core'
include ':nova-dal'
我希望能够使用java -jar build/libs/nova-1.0.0.jar
之类的命令来运行该应用,但目前我正在使用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?
