当guice添加时，ArtifactTransferException eclipse错误

Question

我试图为我的Google App Engine项目添加guice。我使用Maven和Eclipse。在Eclipse中，我根据http://mvnrepository.com/artifact/com.google.inject/guice/3.0将以下内容添加到<dependencies>元素中来修改我的pom.xml：

<dependency>
    <groupId>com.google.inject</groupId>
    <artifactId>guice</artifactId>
    <version>3.0</version>
</dependency>

但是，Eclipse引发了四个错误：

Description Resource    Path    Location    Type
ArtifactTransferException: Failure to transfer com.google.inject:guice:jar:3.0 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact com.google.inject:guice:jar:3.0 from/to central (http://repo.maven.apache.org/maven2): connect timed out pom.xml /audiencemarketing-backend  line 123    Maven Dependency Problem

Description Resource    Path    Location    Type

Description Resource    Path    Location    Type

Description Resource    Path    Location    Type
The project cannot be built until build path errors are resolved    audiencemarketing-backend       Unknown Java Problem

我尝试右键单击我的项目并选择Maven =＆gt;更新项目。但我仍然得到相同的4个错误。我也试过Project =＆gt;干净又相同。

如何根据我的设置正确添加Guice？

Answer 1

我可以通过转到命令行并发出命令mvn clean install来解决此错误。 Maven从Maven Central Repository获取guice库毫无困难。然后我回到Eclipse并右键单击我的项目并选择Maven =＆gt;更新项目。

这解决了我看到的所有错误，让Eclipse感到高兴。
