使用带有 Gradle 的 Spring io 平台，发布任务失败并在生成的 pom 上出现验证错误。似乎 Gradle 发布任务 uploadArchives 和 Maven 发布都希望版本号在生成的 pom.xml 中。当使用 Spring gradle 插件管理依赖版本时，生成的 pom 不包含任何版本号，因此验证失败。为了测试这一点，我基于 STS 中的简单 Gradle 示例创建了一个新项目。然后我改变了 build.gradle 文件如下
buildscript {
repositories { mavenCentral() }
dependencies {
classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.1.1.RELEASE'
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'
apply plugin: 'maven'
repositories {
mavenCentral()
}
dependencies {
versionManagement 'io.spring.platform:platform-versions:1.0.0.RELEASE@properties'
compile 'commons-collections:commons-collections'
}
group = 'someGroup'
organization = 'FooInc'
uploadArchives {
repositories { mavenDeployer { repository(url: "file:c:/gradle/myRepo/") } }
}
运行 Gradle uploadArchives 任务导致异常
* What went wrong:
Execution failed for task ':uploadArchives'.
> Could not publish configuration 'archives'
> Unable to initialize POM pom-default.xml: Failed to validate POM for project someGroup:Foo at C:\Users\Test\Foo\build\poms\pom-default.xml
* Try:
Run with --info or --debug option to get more log output.
* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':uploadArchives'.

如果我更改构建文件以显式添加版本，则上传很好。
