Tomcat嵌入在pom.xml中不工作(SpringBoot 3.0.0 M3)

Question

我正在学习SpringBoot的Udemy课程，但我似乎无法安装其中一个依赖项。本教程要求将Tomcat依赖项导入到pom.xml中(以便从资源中利用JSP页面)，但是在尝试导入之后:

<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId> <!-- Error comes from here -->
<scope>provided</scope>
</dependency>

我在注释行得到以下错误:

Dependency 'org.apache.tomcat.embed:tomcat-embed-jasper:10.0.21' not found

我错过了什么?我使用的是IntelliJ, Java 18.0.1.1，这是我的pom.xml:

我将编辑此文件以提供所需的任何附加信息

Answer 1

您可以删除pom.xml中的<repositories>部分并尝试构建。看起来这个jar在Spring存储库中不可用。如果没有提到，它将从maven中心下载。
