背景

springboot项目是在[SpringInitializr][https://start.spring.io/]中生成的

用gradle, 用不习惯, 就在项目里改成了maven

用的是idea

重启后编译就报错
Error:gradle-resources-test:thymeleaf-in-action.main: java.lang.NoClassDefFoundError: org/apache/tools/ant/util/ReaderInputStream

排除

crtl+shift+alt+s 打开项目结构, 原来这里有main和test两个gradle子模块, 删了.

然后ExcludedFolders里也清一清
