Maven POM.xml 问题 - 顶行出现未知错误 ( <?xml version="1.0" encoding="UTF-8"?> )

Question

我正在使用 Spring 启动项目在 STS 中设置一个项目，并添加所需的依赖项，例如 spring security 和 JSP。但是 pom 文件的第一行抛出未知错误

有人可以帮我解决这个问题吗？

我正在使用STS 4

通常这应该可以正常工作，不会出现任何错误

Answer 1

这是与 Spring Boot 2.1.5 一起使用时的最新惊喜 Eclipse bug，因为 Spring Boot 2.1.5 升级

maven-jar-plugin

到 3.1.2

解决方法是通过将以下内容添加到

pom.xml

来将其降级到以前的版本：

<properties>
    <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

Answer 2

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.4.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
