Spring Boot Devtools 不适用于 Tomcat Embed Jasper

Question

我创建了一个简单的Spring Boot Web应用程序。我需要创建一个应用程序，该应用程序将在具有自动刷新功能的雄猫中运行，这可以通过spring-boot-devtools实现。

每当我在pom.xml中包含spring-boot-devtools maven依赖项时，我都会收到以下错误：

错误

Exception in thread "main" java.lang.IllegalStateException: Failed to read Class-Path attribute from manifest of jar file:/home/chandrashekharkakade/.m2/repository/org/eclipse/jdt/ecj/3.12.3/ecj-3.12.3.jar

和

Caused by: java.util.zip.ZipException: invalid LOC header (bad signature)

暗示/home/chandrashekharkakade/.m2/repository/org/eclipse/jdt/ecj/3.12.3/ecj-3.12.3.jar文件已损坏。您可以检查它是否是有效的zip文件。

要解决此问题，请尝试删除此文件并让 maven 再次下载。
