maven - 意外标记 <!d(位置 : START_DOCUMENT seen\n<! d...@2:4)

Question

我正在尝试通过 maven-publish 在 maven 上发布我的 Gradle 项目插入。

我将我的 Gradle 脚本设置如下build.gradle.kts

apply<MavenPublishPlugin>()

publishing {
  publications.withType<MavenPublication> {

    artifact(javaDocsJar)
    artifact(sourcesJar)

    pom {
      name.set(c.name)
      description.set(c.description)
      url.set(c.siteUrl)
      scm {
        url.set(c.scmUrl)
        connection.set("scm:git:${c.scmConnection}")
        developerConnection.set("scm:git:${c.scmDevConnection}")
      }
    }
  }
  repositories {
    val target = c.organization.takeIf { it.isNotBlank() } ?: c.username
    maven("https://bintray.com/$target/${c.repo}/") {
      credentials {
        username = c.username
        password = c.apiKey
      }
    }
  }
}

之后我运行 ./gradlew publish , 它开始上传 jars/aar/pom 等，但是当涉及到 maven-metadata.xml 我得到了以下异常。

我尝试了 Kotlin 多平台项目、java 项目(混合纯 java/kotlin 模块和 Android)、Android Studio 4.0、IntelliJ Ultimate 2020.1.1、JDK 1.8、JDK 14，使用纯 maven-publish插件和 this plugin .我真的不知道该尝试什么。
我已经尝试从 Robolectric 实现中排除 maven 和 plexus 包，这通常是有问题的......

Kotlin multiplatform project here!

当我错误地使用 bintray pull 存储库名称而不是 push-name 时，我得到了同样的错误。
正确的推送名称是 https://api.bintray.com/maven/$organization/$repository/$project/ .
