java - 如何将源附加到可在 eclipse 外部依赖项中使用的 Gradle (Gradle 6.3.) 构建中的 jar

Question

问题：我有一个 gradle 项目，我在其中使用“pocdemo.jar”作为 gradle 依赖项。当我尝试浏览方法调用层次结构时，它不显示实际代码，而是显示如下图所示的内容

我想为外部依赖附加源，我尝试通过选择 jar -> properties -> Java Source Attachment 来做到这一点，但这不允许我添加源的位置。现在我想知道有没有一种方法可以在 build.gradle 文件中使用，该文件将在 jar 创建过程中包含源代码。我在我的主项目中用作外部依赖项的项目有以下 gradle 文件。

buildscript {
    repositories {
  maven {
            url = repoUrl
            allowInsecureProtocol = true
            metadataSources { 
                mavenPom()
                artifact() 
            }
        }
    maven {
            url = biappsUrl
            allowInsecureProtocol = true
            metadataSources { 
                mavenPom()
                artifact() 
            }
        }
  }
    dependencies {
        classpath(group: 'org.springframework.boot', name: 'spring-boot-gradle-plugin', version: '2.1.3.RELEASE')
    }
}

apply plugin: 'maven-publish'

javadoc {

eclipse {

        downloadJavadoc = true
    }
}
