我在构建项目时出现错误

Question

我在 Spring 框架上有一个项目

当我运行 mvn clean install -DskipTests:

时出现错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project postcodeapp: Compilation failure

这是我的 mvn 和 java 版本：

这是完整的 pom.xml 和 stackTrace：https://gist.github.com/Abdubek/741b4e543b2f376cb2bff42dba447a89

当我启动 mvn clean install 时，创建了目标文件夹并发生错误，然后当我在本地启动时，发生错误

Error: java: java.lang.AssertionError
Error: java: at com.sun.tools.javac.util.Assert.error(Assert.java:126)

如果我删除目标文件夹并再次在本地启动它，则启动成功。但是在我启动 mvn clean install 后没有再次启动。

Answer 1

尝试从您的依赖项中删除尽可能多的 <version> 标记。 Spring Boot 管理了几乎所有流行软件包的版本。让它管理版本。

（注释掉所有版本，只放回出现 Maven 错误的版本）

...

如果还是不行运行...请驱魔人。那个 pom 很大！

Answer 2

我删除了这个文件夹，wsimport过程中出现，赚了

com\microsoft\schemas_2003_10\serialization\ObjectFactory.java

在搜索过程中，我在控制台中注意到

/C:/Users/KazPost/Desktop/citypostkz/back-end/src/main/java/com/microsoft/schemas/_2003/_10/serialization/ObjectFactory.java:[29,8] 重复 class: com.microsoft.schemas._2003._10.serialization.ObjectFactory
