spring 从 1.5.8 引导迁移到 2.1.14-RELEASE 后，BootJar 没有创建 BOOT-INF 文件夹

Question

我已经将 Spring 引导应用程序从 1.5.8 迁移到 2.1.14-RELEASE 并使用 gradle 作为构建脚本。我正在使用 spring-boot-gradle-plugin 和 spring-boot-dependency-management 插件。在我们的 spring 引导项目中，我们通过为每个 jar 创建任务来创建多个可执行 jar 文件，如下所示

// During Migration changed from Jar to BootJar
task eurekaAppJar(type: BootJar) {
    baseName = 'eurekaJar'
    version = '0.0.1'
    println sourceSets.main.output
    manifest {
        attributes 'Main-Class': "org.springframework.boot.loader.JarLauncher"
        attributes 'Start-Class': "com.abc.abcCompany.service.eurekaApp.EurekaApplication"
        attributes 'Implementation-Version': "001"
    }
    bootJar {
        mainClassName = "com.abc.abcCompany.service.eurekaApp.EurekaApplication"
    }
    from(sourceSets.main.output) {
    }
}
// During Migration changed from Jar to BootJar
task oAuthConfigJar(type: BootJar) {
    baseName = 'oAuthConfigJar'
    version = '0.0.1'

    manifest {
        attributes 'Main-Class': "org.springframework.boot.loader.JarLauncher"
        attributes 'Start-Class': "com.abc.abcCompany.service.authserver.AuthServerApplication"
        attributes 'Implementation-Version': "001"

    }
    springBoot {
        mainClassName = "com.abcCompany.service.authserver.AuthServerApplication"
    }
    from(sourceSets.main.output) {
    }
}
// During migration changed from BootRepackage to BootJar
task eurekaBoot(type: BootJar, dependsOn: eurekaAppJar) {
    mainClassName = 'com.abc.abcCompany.service.eurekaApp.EurekaApplication'
// During migration commented the below code
//        customConfiguration = "eurekaconfiguration"
//        withJarTask = eztrackerEurekaJar
}


// During migration changed from BootRepackage to BootJar
task oAuthConfigJarBoot(type: BootJar, dependsOn: oAuthConfigJar) {
    println " Executing eztrackerApiGatewayBoot task"
    mainClassName = 'com.abc.abcCompany.service.authserver.AuthServerApplication'
// During migration commented the below code
//        customConfiguration = "zuulconfiguration"
//        withJarTask = eztrackerApiGatewayJar
}


bootJar.dependsOn = [eurekaBoot, oAuthConfigJarBoot]

bootJar.enabled = false

上面的代码在执行完gradleassemble之后，创建了两个可执行的jar文件eurekaJar-0.0.1.jar, oAuthConfigJar-0.0.1.jar.

这是我的问题：

在spring引导迁移之前，上述jar中的文件夹结构如下：

eurekaJar-0.0.1.jar
   -- 组织
   -- 元信息
   -- 引导-INT
         -- 库
              -- 依赖项（罐子）
         -- 类
               -- 申请类

下面是迁移后的文件夹结构

eurekaJar-0.0.1.jar
   -- 组织
   -- 元信息
   -- 申请类

所以迁移后没有BOOT-INF文件夹和依赖项（lib文件夹）

由于上述问题，我的可执行 jar 不是运行。

如有任何意见，我们将不胜感激。

而不是使用 from，它将文件直接添加到 jar，您应该 configure the classpath BootJar 任务。类路径上的 Jar 文件将打包在 BOOT-INF/lib 中，目录将打包在 BOOT-INF/classes.

中

作为参考，您可以查看 Spring Boot 如何在自己的插件 here 中配置默认 bootJar 任务的类路径。从上面显示的内容来看，您可能也想使用主要源代码集的运行时类路径。

这是您 eurekaAppJar 的完整示例：

import org.springframework.boot.gradle.tasks.bundling.BootJar

plugins {
    id 'org.springframework.boot' version '2.1.4.RELEASE'
    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()
}

task eurekaAppJar(type: BootJar) {
    baseName = 'eurekaJar'
    version = '0.0.1'
    manifest {
        attributes 'Main-Class': "org.springframework.boot.loader.JarLauncher"
        attributes 'Start-Class': "com.abc.abcCompany.service.eurekaApp.EurekaApplication"
        attributes 'Implementation-Version': "001"
    }
    mainClassName = "com.abc.abcCompany.service.eurekaApp.EurekaApplication"
    classpath sourceSets.main.runtimeClasspath
}

然后可以使用以下命令构建此 jar：

$ ./gradlew eurekaAppJar

其类和依赖分别打包在BOOT-INF/classes和BOOT-INF/lib中：

$ unzip -l build/libs/eurekaJar-0.0.1.jar 
Archive:  build/libs/eurekaJar-0.0.1.jar
