我的grails-flyway插件的传递依赖存在问题。org.grails.plugins:grails-flyway:0.2.1声明对org.flywaydb:flyway-core:4.0.1. 当我将插件包含到我的 Grails 3.1.6 项目中时，Gradle 将 Flyway 降级到版本 3.2.1。

+--- org.grails.plugins:grails-flyway:0.2.1
|    \--- org.flywaydb:flyway-core:4.0.1 -> 3.2.1

我的 Gradle 构建文件如下所示

buildscript {
    ext {
        grailsVersion = project.grailsVersion
    }
    repositories {
        maven { url "https://repo.grails.org/grails/core" }
    }
    dependencies {
        classpath "org.grails:grails-gradle-plugin:$grailsVersion"
        classpath "com.bertramlabs.plugins:asset-pipeline-gradle:${assetPipelinePluginVersion}"
        classpath "org.grails.plugins:hibernate5:5.0.5"
        classpath 'com.github.ben-manes:gradle-versions-plugin:0.12.0'
    }
}

}

task wrapper(type: Wrapper) {
    gradleVersion = gradleWrapperVersion
}

assets {

    minifyCss = true
}

目前我不明白为什么 Gradle 会降级我的传递依赖。有人可以提供这个吗？

我知道我可以强制flyway-core:4.0.1依赖我build.gradle，但我想了解降级的原因。

更新-1

当我运行时，gradle dependencies | grep flyway我得到以下输出。

+--- org.grails.plugins:grails-flyway:0.2.1
|    \--- org.flywaydb:flyway-core:4.0.1 -> 3.2.1
+--- org.grails.plugins:grails-flyway:0.2.1
|    \--- org.flywaydb:flyway-core:4.0.1 -> 3.2.1
+--- org.grails.plugins:grails-flyway:0.2.1
|    \--- org.flywaydb:flyway-core:4.0.1 -> 3.2.1
+--- org.grails.plugins:grails-flyway:0.2.1
|    \--- org.flywaydb:flyway-core:4.0.1 -> 3.2.1

请在pastebin找到完整的输出。该grails-flyway插件及其 pom.xml 可以在Bintray找到。

更新-2

我试图强制 Gradleorg.flywaydb:flyway-core:4.0.1根据Gradles Reference使用。

configurations.all {
    resolutionStrategy.force 'org.flywaydb:flyway-core:4.0.1'
}

这不影响问题。依赖关系树仍然使用 3.2.1 版本的flyway-core.

+--- org.grails.plugins:grails-flyway:0.2.1
|    \--- org.flywaydb:flyway-core:4.0.1 -> 3.2.1

更新-3

摇篮dependencyInsight命令

gradle dependencyInsight --dependency flyway-core --configuration runtime

结果是

:dependencyInsight
org.flywaydb:flyway-core:3.2.1 (selected by rule)

org.flywaydb:flyway-core:4.0.1 -> 3.2.1
\--- org.grails.plugins:grails-flyway:0.2.1
     \--- runtime

什么意思(selected by rule)？

“解决方案” - 或如何解决

我找不到导致 Gradle 使用flyway-core:3.2.1而不是flyway-core:4.0.1. 但我找到了解决这个问题的方法。

我添加了以下内容来build.gradle修改我的 Gradleruntime解析策略。

configurations.runtime.resolutionStrategy {

    eachDependency { DependencyResolveDetails det ->

        if (det.requested.name == 'flyway-core' && det.requested.group == 'org.flywaydb') {
            det.useVersion(det.requested.version)
        }
    }
}

造成它的原因是spring-boot-dependencies-1.3.3.RELEASE.pom

这迫使 flyway 版本为 3.2.1

根据Spring Boot 文档，您应该能够将这样的行添加到您的build.gradle： ext['flyway.version'] = '4.0.1'

转到您的 Gradle 缓存文件文件夹：

cd ~/.gradle/caches/modules-2/files-2.1

搜索此版本号：

grep -r "3.2.1" *

你会发现哪个 pom 文件正在使用这个版本，通常它在spring-boot-dependencies-x.y.z.RELEASE.pom：

<flyway.version>3.2.1</flyway.version>
......
<groupId>org.flywaydb</groupId>
    <artifactId>flyway-core</artifactId>
    <version>${flyway.version}</version>
</dependency>

这意味着，如果您使用spring-boot，它将覆盖一些依赖版本。

您可以通过在gradle.properties文件中添加以下行来再次覆盖它：

flyway.version=4.0.1

我遇到了类似的问题并浪费了几个小时。所以我把这些信息留在这里，希望如果你遇到这个问题，这可以节省你的时间
