Question

gradle从1.12升级到2.14后，未识别maven存储库中依赖项的快照版本。存储库已正确设置，maven-metadata.xml和依赖项存在，并使用1.xx版本的gradle构建。无法从2.xxx的gradle发行说明中找到任何内容。有人遇到过这种情况吗？以下是我的build.gradle文件。

// Apply the java plugin to add support for Java
apply plugin: 'java'

// In this section you declare where to find the dependencies of your project
repositories {
// Use 'maven central' for resolving your dependencies.
// You can declare any Maven/Ivy/file repository here.
mavenCentral()
 maven {
    name = 'Public'
    credentials {
        username = 'abc'
        password = 'abc'
    }
    url 'http://mydomain/nexus/content/groups/public/'
}

}

// In this section you declare the dependencies for your production and test   code
dependencies {
// The production code uses the SLF4J logging API at compile time
compile( 

[group: 'com.test.comp', name: 'comp-app-interface', version: "3.0.9_SNAPSHOT"],
[group: 'com.test.comp', name: 'comp-app-common', version: "3.0.10_SNAPSHOT", classifier: 'lib'],
)
// Declare the dependency for your favourite test framework you want to use in your tests.
// TestNG is also supported by the Gradle Test task. Just change the
// testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add
// 'test.useTestNG()' to your build script.
testCompile "junit:junit:4.11"
}

以下是使用gradle 2.14构建时出现的错误消息：

但是当使用gradle 1.12构建时，它会下载正确的快照。

Answer 1

该错误表示所需的依赖项i>0不在任何指定的存储库中。请先检查gradle是对还是错（通过查看给定的存储库）。

要更正错误，请检查是否包含所有相关存储库。如果错误仍然存在，请删除本地Maven存储库和Gradle缓存，然后重试。

Answer 2

我发现并解决了这个问题。由于版本号的格式，Gradle不会识别它们是快照。例如：当版本号和快照之间有下划线时，3.0.9_SNAPSHOT gradle只是查找该版本的依赖关系。但如果它之间有一个破折号而不是下划线（即3.0.9-SNAPSHOT），gradle将读取maven-metadata.xml并找到最新的快照。使用gradle 1.xxx版本时，下划线工作正常。

在从1.12到2.14的gradle升级后无法找到快照依赖项
