【问题描述】：

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:

              - 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)

              - 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
    }
}

我不知道该怎么做。项目 JDK 和 Gradle JVM 设置为 Java 11。这篇文章在这里： The consumer was configured to find a runtime of a library compatible with Java 11, packaged as a jar, and its dependencies declared externally but: ...属于同样的问题，但没有帮助我。

知道这里发生了什么吗？

标签： java gradle intellij-idea java-11

【解决方案1】：

好的，我发现了问题。

build.gradle 文件中有以下两行：

 sourceCompatibility = 10
 targetCompatibility = 10

他们需要更改为 11。然后它起作用了。

【讨论】：

我们团队也遇到了这个问题。这是由使用另一个 JVM 的 IntelliJ 的 Gradle 版本引起的。要解决此问题，请转到首选项：Build, Execution, Deployment > Build Tools > Gradle > Gradle JVM 并在那里更改 jvm 版本
谢谢@jvwilge，在声明 sourceCompatibility/targetCompatibility 后我花了一个小时左右挠头，但仍然面临这个问题！
同样，感谢@jvwilge，已经为它奋斗了几个小时。
谢谢@jvwilge 我很困惑为什么它仍然提到 Java 8，即使我在项目设置中将 JDK 设置为 11。
@jvwilge 你是我的英雄

【解决方案2】：

就我而言，这与 Java 版本无关。它仍然存在1.8 (8). 如果你使用的是最新版本的 Kotlin，你应该更新你的摇篮版本至6.7.1或者更高在项目结构. 我建议改变Gradle 插件版本到最新稳定版.
