Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory in Spring tool suite

Question

我正在使用 Spring 工具套件（版本：3.7.1.RELEASE）并尝试创建简单的 spring maven project.I 在 [=17] 中添加了依赖项=].当我使用我的台式机时它工作正常，当我试图在我的笔记本电脑上使用同样的东西时它给了我上述错误。我也试过手动下载 jar 文件，但没有成功。谁能帮我？我的 pom.xml 附在下面。

我已将 java 从 1.7 升级到 1.8，并在 STS 中将 jre 1.8 作为运行时间环境。这解决了我的问题。
