不兼容，因为该组件声明了一个与 Java 11 兼容的组件，而使用者需要一个与 Java 10 兼容的组件

Question

在我的 build.gradle 文件中，我升级了一个依赖项的版本（即：com.db:microservice-commons）。加载 gradle 更改后，我收到以下错误消息：

> Build file 'C:\Projects\Container\mschmidt\mount\booking-service\standalone\build.gradle' line: 50

   > A problem occurred evaluating project ':standalone'.
   > Could not resolve all files for configuration ':standalone:runtimeClasspath'.
   > Could not resolve com.db:microservice-commons:2.4.1.
     Required by:
         project :standalone
         project :standalone > project :service
      > No matching variant of com.db:microservice-commons:2.4.1 was found. The consumer was configured to find a runtime of a library compatible with Java 10, packaged as a jar, preferably optimized for standard JVMs, and its dependencies declared externally but:
          - Variant 'apiElements' capability com.db:microservice-commons:2.4.1 declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component compatible with Java 11 and the consumer needed a runtime of a component compatible with Java 10
              - Other compatible attribute:
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
          - Variant 'runtimeElements' capability com.db:microservice-commons:2.4.1 declares a runtime of a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 10
              - Other compatible attribute:
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
          - Variant 'samplessources' capability com.db:microservice-commons:2.4.1:
              - Incompatible because this component declares documentation and the consumer needed a library
              - Other compatible attributes:
                  - Doesn't say anything about how its dependencies are found (required its dependencies declared externally)
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
                  - Doesn't say anything about its target Java version (required compatibility with Java 10)
                  - Doesn't say anything about its elements (required them packaged as a jar)
                  - Doesn't say anything about its usage (required a runtime)

文件“C:\Projects\Container\mschmidt\mount\booking-service\standalone\build.gradle”的第 50 行以上如下所示：

manifest {
    def manifestClasspath = configurations.runtimeClasspath.collect { it.getName() }.join(' ')
    attributes 'Archiver-Version': 'Plexus Archiver'
    attributes 'Build-Jdk': org.gradle.internal.jvm.Jvm.current()
    attributes 'Main-Class': 'com.db.service.standalone.Standalone', 'Class-Path': manifestClasspath
    }
}

我不知道该怎么办。项目 JDK 和 Gradle JVM 设置为 Java 11。这里的这篇文章： 消费者被配置为查找与 Java 11 兼容的库的运行时，打包为 jar，其依赖项在外部声明，但是： ...属于相同的内容问题但没有帮助我。

有什么想法吗？

Answer 1

使用 IntelliJ IDEA，我必须更改用于运行的 JDK Gradle。原来的值为JDK 11，我将其更改为JDK 17。

Answer 2

我发现了问题并解决了它。

我更改了定义文件中兼容性的两行build.gradle。

从：

compileOptions {
    sourceCompatibility 10
    targetCompatibility 10
}

到：

compileOptions {
    sourceCompatibility 11
    targetCompatibility 11
}

Answer 3

更改gradle使用的java版本。如下图，选择java 11就可以了。
