Question

我正在尝试将log4j添加为Maven依赖项。所以我把它添加到pom.xml

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.15</version>
</dependency>

现在我有一条警告消息，我遗漏了6件工件（log4j所依赖的罐子）。如以下网站Maven Repository - log4j所述。

我的目标是让Maven为我安装6个依赖项。我有嵌入式Maven的Eclipse Kepler，所以我无法运行＆＃34; mvn install＆＃34;。我从这个stackoverflow回答Run Maven Install in Eclipse看到我可以右键单击该项目并运行为＆gt; Maven安装。但是我收到以下错误：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

如果我走在正确的道路上，请告诉我以及如何最好地获取log4j依赖项。提前感谢您的帮助。

更新检查首选项＆gt; Maven＆gt;用户设置，我发现正在引用的settings.xml文件不存在。我点击了＆＃34;更新设置＆＃34;我收到以下错误：

ArtifactTransferException: Could not transfer artifact com.sun.jdmk:jmxtools:jar:1.2.1 from/to java.net (https://maven-repository.dev.java.net/nonav/repository): No connector available to access repository java.net (https://maven-repository.dev.java.net/nonav/repository) of type legacy using the available factories AsyncRepositoryConnectorFactory, WagonRepositoryConnectorFactory

更新2
看起来我的问题是Maven 3（随Kepler一起提供）试图访问Maven 2存储库并存在兼容性问题。我还没弄明白如何重定向到适当的存储库。

Answer 1

我将版本从1.2.15更改为1.2.17并且它有效（1.2.16也可以）。我没有看到任何列出的依赖项＆＃34; here＆＃34;在Resolved Dependencies框架中列出，就像我在1.2.15中所做的那样。我没有完全理解为什么这样有效，但它对我有用。

Answer 2

您可以右键单击您的项目，然后Maven＆gt;更新快照。（确保您选中“强制更新快照”复选框。这应该有效。

使用Eclipse中嵌入的Maven来安装依赖项
