spring - gradle 在 mavenLocal 存储库中找不到 jar

Question

我依赖 spring-beans;4.0.0.RELEASE，我使用它安装到我的 mavenLocal 缓存中
mvn install:install-file -Dfile=/Users/jric/Downloads/spring-beans-4.0.0.RELEASE.jar -DpomFile=/Users/jric/Downloads/spring-beans-4.0.0.RELEASE.pom ,

但是 gradle-1.11 没有找到依赖项，没有太多解释。我确实找到了这个看起来很相关的堆栈跟踪:

11:26:35.432 [DEBUG] [org.gradle.api.internal.artifacts.ivyservice.ivyresolve.RepositoryChainDependencyResolver] Discarding resolve failure.
java.lang.NullPointerException
        at org.gradle.api.internal.artifacts.repositories.resolver.MavenLocalResolver.isOrphanedPom(MavenLocalResolver.java:49)

        at org.gradle.api.internal.artifacts.ivyservice.ivyresolve.memcache.CachedRepository.getLocalDependency(CachedRepository.java:67)

以下是一些更可能相关的数据:

Gradle 有一个特殊的语句可以在本地 Maven 存储库中查找:mavenLocal()。确保在全局存储库部分调用它:

repositories {
    mavenLocal()  // <- Here
    mavenCentral()
}

如果它不起作用，请确保您没有在 buildscript 部分无意中添加它。这会将依赖项添加到您的构建环境而不是您的代码，这通常不是您想要的。

buildscript {            // <- Probably not what you mean
    repositories {
        mavenLocal()
        mavenCentral()
    }
}
