错误：Maven2RepositoryLayoutFactory：不支持的仓库布局legacy。

我有一个几乎空白的Spring项目，其中包含log4j。Log4j是这样注册的：

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

在pom.xml中显示您的存储库配置。 - Jens

pom.xml 中没有添加额外的存储库。 - JRr

Answer 1

我知道两个解决方案：

1. 将log4j版本更新为1.2.17可解决该问题。

2. 保持log4j版本为1.2.15，但通过添加运行时作用域来解决问题，方法如下：

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

谢谢@joro，你刚刚为我节省了一些时间！;) - Archer

还有一种方法，请参见https://crunchify.com/maven-artifacts-error-jms-jmxtools-jmxri-dependencies/。 - T. Cervenka

Answer 2

我发现解决这个问题的唯一方法是创建一个简单的Maven 2项目，将失败的依赖项放入其中。然后我运行Maven 2来构建这个项目，依赖项可以正常下载，然后Maven 3就能找到它们了。

我尝试使用更新策略“always”，但并不总是有效。
