spring-boot - Spring Boot 1和Gradle:ClassNotFoundException SpringApplicationBuilder

Question

我已经为Spring Boot 1.5应用程序配置了Gradle。它可以在Spring Tool Suite中正常运行，但是gradlew build创建的jar文件在BOOT-INF文件夹中没有jar文件。这当然会阻止jar文件的成功执行:

java -jar build\libs\myapp-0.0.1-SNAPSHOT.jar

build.gradle摘录:

plugins {
    id 'org.springframework.boot' version '1.5.22.RELEASE'
    id 'java'
}

dependencies {
    implementation('org.springframework.boot:spring-boot-starter-web')
    implementation('org.springframework.boot:spring-boot-starter-jdbc')
    implementation('org.springframework.boot:spring-boot-starter-data-jpa')
    ...
}

Answer 1

事实证明，Spring Boot 1不能使用implementation依赖项，但是可以使用(不建议使用)compile依赖项。
工作的build.gradle依赖项:

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-jdbc')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    ....
}
