Maven 找不到带有Gradle的slf4j LoggerFactory类定义

我正在尝试构建并运行一个Spark Web服务器，该服务器使用IntelliJ中的slf4j登录。它在最初用于添加日志记录的计算机上（但不是在我的机器上）的IntelliJ中也可以很好地构建

以下是使用记录器的部件的完整build.gradle文件，请参见项目“：webserver”：

我已经研究了几个关于StackOverflow的问题，但似乎没有一个能解决这个问题：

-我正在和gradle一起构建，不认为我应该在我的类路径中下载/放置一些jar -同上 -又是罐子的东西 -我不确定胖jar/ShadowJar是否适用，也不确定如何修改构建文件以使用它们 -我尝试过多次刷新gradle，重启IntelliJ，甚至重启电脑 -见下文 我尝试了以下依赖项：

编译组：“org.slf4j”，名称：“slf4j-log4j12”，版本：“1.6.1” 编译“org.slf4j:slf4j api:1.7.24”并编译“org.slf4j:slf4j simple:1.7.24” 编译组：“org.slf4j”，名称：“slf4j simple”，版本：“1.6.1”

---

所有这些似乎都没有什么不同。有什么想法吗？

我最终删除了我的Gradle cache.Gradle文件夹并重新下载了所有内容，这解决了问题。

如果您使用的是Gradle，请将这两行添加到您的build.Gradle依赖项中以使用Spark 2.6.0

编译com.sparkjava:sparkcore:2.6.0

---

编译组：'org.slf4j'，名称：'slf4j simple'，版本：'1.7.21'

在执行过程中，类路径中似乎没有slf4j api。@Henry我如何添加它？如果我使用gradle，我不应该下载它并把它放在某个地方，对吗？它不应该处理好吗？感谢您将slf4j api添加到编译依赖项中，请使用与slf4j-log4j12相同的版本。@Henry我将其更改为编译组：“org.slf4j”，名称：“slf4j-log4j12”，版本：“1.6.1”，编译组：“org.slf4j”，名称：“slf4j api”，版本：“1.6.1”，刷新了gradle，并尝试再次运行服务器，但我也犯了同样的错误。服务器是由gradle启动的，还是以另一种方式启动的？他尝试了许多方法，这是为了澄清，假设一个干净的缓存是实现这一点的最简洁的方法，并且具有Spark 2.6.0官方文档中提供的slf4j版本号
