Maven为什么要下载log4j-1.2.17.jar？

Question

我有一个用 Maven 构建的 Mule 应用程序。我试图确保它在构建时不会下载 log4j-1.2.17.jar。然而， 罐子出现在

repository/log4j/log4j/1.2.17/log4j-1.2.17.jar

此版本的 log4j 不是我的任何依赖项的依赖项。这是

mvn dependency:tree

的输出：

Log4j 1.2.17 没有出现在这里

我发现之前问过这个问题：Why is Maven downloading log4j-1.2.12.jar? 但问题是

maven-compiler-plugin

正在下载 log4j。我没有这个插件。 我唯一的插件是

mule-maven-plugin 3.3.5

，

maven-resources-plugin 3.0.2

和

munit-maven-plugin 2.2.5

为什么这个 jar 出现在我的文件路径中？

Answer 1

你的

log4j-1.2.17

是通过Maven插件下载的。

这没有害处，您可以放心地忽略它。它不会成为您构建的应用程序的一部分。
