问题： 我从 Java 11 更新了我的 JDK JAVA 17。但是当我想构建我的 spring 项目时遇到了一些问题，当我执行 maven install 时出现错误：
[INFO]
[INFO] Results:
[INFO]
[ERROR] Errors:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-failsafe-plugin:3.0.0-M1:verify (default) on project myapp-bo: There are test failures.
我所做的 ：
- 将 JAVA JDK 更新到 17
- 在我的 pom.xml 中：
- 添加 <java.version>17</java.version>
- 更改 jacoco-maven-plugin 0.8.7 的版本（0.8.6 之前）
- 添加 maven-surefire-plugin 和 maven-failsafe-plugin : 3.0.0-M1
- 将 spring-boot-starter-parent 更新为：2.4.13
[2022 年 2 月 2 日更新 13:38]
- 当我安装 maven 时，我没有错误：BUILD SUCCESS
- 当我作为 java 程序运行时，我有一些错误： 问题：这是什么意思？
2022-02-02 13:37:06.549 DEBUG 27549 --- [ restartedMain] Validator : ERROR[ModelSpecification.spec] 至少需要一种规范
这是我的 pom.xml：
