java - 混合 scala/java gradle 项目无法正确加载依赖项
问题描述
我在使用 gradle 编译混合 Java/Scala 项目时遇到问题。我有 Java 类src/main/java和 scala 类src/main/scala。到目前为止，我使用 maven 没有任何问题，但现在我需要将其转换为 gradle。
我遇到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，我还使用了本地工件的自己的依赖项，最终的build.grade 看起来与此类似
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，我包括了 sourceSets。我发现这应该可以解决问题，不幸的是，我自己的依赖存在问题，并且出现如下错误：

似乎 scala 在从build.gradle获取依赖项方面存在问题。我找不到有关如何修复它的任何信息。
