正在将 Gradle 5.3.1 升级到 6.5。旧版本下载依赖正常，但在 6.5 上失败
Upgrading Gradle 5.3.1 to 6.5. Older version downloaded dependency OK, but fails on 6.5
我已将我的问题缩减为一个非常简单的项目，该项目声明了对从我的客户的工件实例提供的模块工件的模块依赖性。
这适用于 5.3.1。从下面的日志中可以看出，有一行表明 DefaultExternalResourceArtifactResolver 正在加载相关的
.jar 用于我的 maven2 存储库中的此依赖项（请参阅：{{{ A }}}）
但是，当我尝试升级到 Gradle 6.5 时，我收到消息
org.gradle.api.internal.artifacts.ivyservice.ivyresolve.CachingModuleComponentRepository] Detected non-existence of module 'com.mouse.ap.data.qe:lib-reptile-generator:0.1-806-SNAPSHOT' in resolver cache 'maven2'

重要脚注：如果您遵循接受的答案中给出的好的建议，请确保避免我的愚蠢错误：不要将推荐的 'metadataSources' 块放在 buildscript { repositories 那肯定不是你想要的！
根据您的评论
there is no metadata of any kind (no pom, etc), just the .jar
您的存储库仅包含 jar 文件并且缺少元数据 pom 文件。在 6.0 之前，Gradle 尝试首先从 pom 派生元数据，然后如果缺少 pom 则尝试生成工件。 Gradle 6 改变了这一点。出于效率原因，默认元数据源仅为 gradleMetadata() 和 mavenPom()。因此，如果两者都缺失，Gradle 似乎不会尝试下载 jar。
要恢复旧行为并能够解决依赖关系，请将 artifact() 添加到您的 Maven 存储库 metadataSources 配置。
repositories {
['animals'].each { repo ->
maven {
name repo
url "${urlDefinedInGradleProperties}/${repo}"
credentials {
username = 'mouse'
password = 'mouse.mouse'
}
metadataSources {
mavenPom()
artifact()
}
}
}
}
您可以在文档中阅读更多相关信息 Supported metadata sources。

重要脚注：如果您遵循接受的答案中给出的好的建议，请确保避免我的愚蠢错误：不要将推荐的 'metadataSources' 块放在 buildscript { repositories 那肯定不是你想要的！
根据您的评论
there is no metadata of any kind (no pom, etc), just the .jar
您的存储库仅包含 jar 文件并且缺少元数据 pom 文件。在 6.0 之前，Gradle 尝试首先从 pom 派生元数据，然后如果缺少 pom 则尝试生成工件。 Gradle 6 改变了这一点。出于效率原因，默认元数据源仅为 gradleMetadata() 和 mavenPom()。因此，如果两者都缺失，Gradle 似乎不会尝试下载 jar。
要恢复旧行为并能够解决依赖关系，请将 artifact() 添加到您的 Maven 存储库 metadataSources 配置。
repositories {
['animals'].each { repo ->
maven {
name repo
url "${urlDefinedInGradleProperties}/${repo}"
credentials {
username = 'mouse'
password = 'mouse.mouse'
}
metadataSources {
mavenPom()
artifact()
}
}
}
}
