我尝试使用命令 mvn clean install 通过 commandpromt 构建一个 springboot 应用程序，但它给出了以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project infytel_demo7_a: Compilation failure: Compilation failure:

我正在使用 java 8 和 spring boot 2.2.1.Release .PFB 图像。

PFB pom 文件：

我做了以下事情： --> 试图从 .m2 文件夹中删除存储库。 -->在pom中添加了maven编译器插件。

我在 jaxb-api 文件夹中有这么多东西：

你能帮我解决这个问题吗？

【问题讨论】：

javax.xml.bind.annotation 包应该在jaxb-api jar 文件中。我会仔细检查.m2/repository 中该文件的副本是否是有效的 zip 文件并包含预期的类。
能否请您提及 .m2/repository 文件夹中 jax-api 的路径
我已经添加了有问题的截图
它来自模块的组 ID、工件 ID 和版本。组 ID 中的 .s 替换为 /s。在这种情况下，这给出了.m2/repository/javax/xml/bind/jaxb-api/2.3.1/jaxb-api-2.3.1.jar 的路径。 Maven 下载的每个依赖项都使用相同的模式。
我在通过命令 promt 运行时遇到了这个问题。如果我通过 Eclipse 使用命令 clean install -X 运行它就成功了

【解决方案1】：

我使用的是 JDK 11，当我将 JAVA_HOME 和 Path 环境值指向 JDK 1.8.0_311 时。这个问题得到了解决。希望对你有帮助
