使用Idea进行mvn编译工作正常。
在应用程序主启动期间失败。
在Ubuntu上的其他PC上的旧想法上工作得很好。
环境变量：

  • Intellij 2020.3.2作为管理员;
  • Java语言15.02;
  • Windows 10 x64;
  • 最新Map结构。

如何解决这个问题？

我在Intellij 20.3.2中遇到了MapStruct的问题。错误 * Map处理器中的内部错误：java.lang.NullPointerException：Cannot invoke“java.net.URL.toExternalForm（）”，因为“resource”为null[...]。* 我做了一点研究，发现只需更改pom. xml中的版本就足够了。在文档网站上，我们可以看到包安装配置：https：**//mapstruct.org/documentation/installation/**在以下摘录中仍然存在错误：

  1. <groupId>org.mapstruct</groupId>
  3.   <artifactId>mapstruct</artifactId>
  5.   <version>**${org.mapstruct.version}**</version>

字符串
最后，在1.4.2.Final中放置以下版本，应用程序可以顺利运行。

请更新到当前IDE和MapStruct版本。此问题已在很久以前修复。
另请参见this answer了解解决方法。

请更新newVersionMap结构

  1. <dependency>
  2.     <groupId>org.mapstruct</groupId>
  3.     <artifactId>mapstruct</artifactId>
  4.     <version>1.4.2.Final</version>
  5. </dependency>

确保你使用的是相同版本的mapstruct和mapstruct-processor：

  1. <dependency>
  2.     <groupId>org.mapstruct</groupId>
  3.     <artifactId>mapstruct-processor</artifactId>
  4.     <version>1.5.3.Final</version>
  5. </dependency>
  7. <dependency>
  8.     <groupId>org.mapstruct</groupId>
  9.     <artifactId>mapstruct</artifactId>
  10.     <version>1.5.3.Final</version>
  11. </dependency>
