gradle似乎无法加载javax.inject。因此，我得到了下面提到的错误

变通我将guice的依赖项直接添加到项目的build.gradle中

compile group: 'aopalliance', name: 'aopalliance', version: 1.0
compile group: 'javax.inject', name: 'javax.inject', version: 1
compile group: 'org.sonatype.sisu.inject', name: 'cglib', version: '2.2.1-v20090111'
compile group: 'asm', name: 'asm', version: 3.1

问题

它就像黑客一样工作，但需要任何真正的修复

查看我的项目所需的其他jar，它们在META-INF>maven>lib name folder hierarchy>pom.xml中定义了依赖项，但这个guice-3.0.jar在META-INF>dependencies文件中定义了依赖项。这种不同的惯例会引起任何问题吗

原始问题对于我的一个java项目，我执行了

gradlew--refresh dependencies

，项目构建

compileJava

任务开始抛出以下错误：

:myproject:compileJava
/<path-to-my-project/MyProvider.java:24: error: cannot access Provider
public class MyProvider<T> implements Provider<T> {

这是openJDK

嗯，我的队友们，他们没有执行过gradlew--refresh dependencies，他们没有面临这样的问题。我不认为这是java编译器的问题，但似乎是gradle的问题

当我使用eclipse检查时，MyProvider.java引用guice-3.0.jar中的com.google.inject.Provider

com.google.inject.Provider是指javax.inject.Provider，它似乎不包含在依赖项中

有什么解决办法吗

有什么方法可以回滚“刷新依赖项”命令吗

有什么解决办法吗

我执行了cleanEclipse，eclipse，将gradle升级到3.5，然后降级到2.14.1，但运气不好

向java报告了类似的问题，但由于无法重现，该问题被关闭：。

您是否尝试将

javax.inject:javax.inject:1

添加到依赖项中？@BjørnVester，是的，将这些依赖项直接添加到我的项目工作中，但我想gradle应该注意这一点。我更新了我的问题，询问如何强制gradle处理依赖项的依赖项。gradle不使用META-INF中的元数据文件，如

dependencies

和

pom.xml

来解析依赖项。我甚至不认为Maven使用嵌入式的。相反，存储库中jar文件旁边应该有一个pom文件。我见过一些组织拥有自己的Maven存储库，它们在其中手动上载库，但会破坏原始pom文件，从而破坏所需的可传递依赖项。也许你可以看看你的情况是否如此？@BjørnVester，是的，我们有自己的Maven存储库。guice jar是从以下位置引用的：~/.gradle/caches/modules-2/files-2.1/com.google.inject/guice/3.0/9d84f15fe35e2c716a02979fb62f50a29f38aefa/guice-3.0.jar。我查看了当前POM文件的位置：~/.gradle/caches/modules-2/files-2.1/com.google.inject/guice/3.0/5A1068122BA3584F77006351BFAD65F302BCC/guice-3.0.POM。它不包含任何关于依赖项的标记/信息。而早期的guice-3.0.pom确实包含关于依赖项的标记/信息。这就是问题吗？是的，这看起来是个问题。如果您可以找到对公司存储库的依赖关系，pom文件可能在那里是空的，这将是一个错误。最好的解决方案是修复存储库中的pom文件，然后使用

--刷新依赖项

运行构建。如果这是不可能的，并且您的公司策略允许，您可以将依赖项配置为从Maven Central或JCenter加载。如果这也不可能，我想你别无选择，只能像以前那样解决每个消费项目中的问题……你是否尝试过将

javax.inject:javax.inject:1

添加到依赖项中？@BjørnVester，是的，将这些依赖项直接添加到我的项目中，但我想，格雷德尔应该负责这件事。我更新了我的问题，询问如何强制gradle处理依赖项的依赖项。gradle不使用META-INF中的元数据文件，如
