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
Missing artifact com.google.inject:guice:jar:3.0    pom.xml /audiencemarketing-backend  line 1  Maven Dependency Problem

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。

当guice添加时，ArtifactTransferException eclipse错误
