gradle - Spring Boot应用程序的Gradle构建异常

Question

我试图在Eclipse中使用Gradle运行Spring Boot应用程序。它给bootRun一个异常(exception)。我尝试了几乎所有与此异常(exception)相关的组合。我试图在 Spring 启动应用程序中排除冲突的tomcat jar。但是它没有用。

异常(exception):

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is java.lang.NoSuchMethodError: javax.servlet.ServletContext.getClassLoader()Ljava/lang/ClassLoader;

Answer 1

尝试以下命令:

./gradlew clean

而这个命令:

./gradlew build

它应该修复bootRun异常。
