混合Scala / Java Gradle项目无法正确加载依赖项

我在使用gradle编译Java / Scala混合项目时遇到问题。我有Java类，js src/main/java 而
Scala 有类js src/main/scala 。
至此，我在使用maven时没有任何问题，但是现在我需要将其转换为gradle。

我的问题是在复杂过程中看不到scala类。我通过定义源集找到了解决此问题的可能方法，我还使用了来自本地工件的依赖项，最终的build.gralde 与此类似

buildscript {
    dependencies {
        classpath "org.springframework.boot:spring-boot-gradle-plugin:2.1.3.RELEASE"

    }
}

apply plugin: 'scala'
apply plugin: 'org.springframework.boot'

group = 'some.package'
sourceCompatibility = 1.8
targetCompatibility = 1.8


dependencies {
    compile 'org.springframework.boot:spring-boot-starter-web:2.0.3.RELEASE'
    compile 'org.scala-lang:scala-library:2.11.12'
    compile 'org.scala-lang:scala-compiler:2.11.12'
    compile 'my.dependency:artifact:version'
}

sourceSets {
    main.scala.srcDirs = ["src/main/scala", "src/main/java"]
    main.java.srcDirs = []
}

wrapper {
    gradleVersion = '5.1.1'
}

如您所见，我包含了sourceSets。我发现这应该可以解决问题，不幸的是，与此相关的是我自己的依赖项存在问题，并且出现了如下错误：

似乎scala在从build.gradle获取依赖项时遇到问题。我找不到有关如何解决它的任何信息。
