Maven错误无法访问属性的默认字段

2022-08-10 00:00:00 java maven pom.xml
我使用的是最新版本的JAVA-&>16。当我运行MVN CLEAN时,收到无法初始化类org.apache.maven.plugin.war.util.WebappStructureSerializer错误。我读到添加maven-war-plugin可能是一种解决方案,但它对我不起作用。当我运行MVN安装时,出现以下错误:

注入构造函数时出错,java.lang.ExceptionInInitializerError: 无法访问位于的属性的默认字段 (来源不详) 查找org.apache.maven.plugin.war.WarMojo

如何解决这些问题?它们是由Java版本引起的吗?

更改pom.xml中的WAR插件版本,并根据您的推荐答案版本添加maven-compiler-plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.3.1</version>
</plugin>
<plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.1</version>
</plugin>
