Java 17 条记录 class 出现 UnknownElementException
UnknownElementException on Java 17 record class
今天兴奋地下载了Java17，简单记录了下class
public record TestCls(Party producer, Party client, Party server) {}
但是当做 mvn compile 时，它会抛出错误
Fatal error compiling: javax.lang.model.element.UnknownElementException: Unknown element: "com.xxx.TestCls"
我仔细检查了 java -version，我认为它是对的：
openjdk version "17" 2021-09-14
OpenJDK Runtime Environment (build 17+35-2724)
OpenJDK 64-Bit Server VM (build 17+35-2724, mixed mode, sharing)
有人知道吗？提前致谢！
补充：
我的 Maven 版本是 3.5.4.
pom 文件中的 Maven 设置：
<properties>
<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
我在 M1 芯片上使用 Intellij 2021.1.2。但是我在终端中尝试了 mvn compile，它给了我同样的错误。
Party class 在同一项目中定义。

显然，按照评论中的建议升级 Maven 和 maven-compiler-plugin 的版本会更安全。尽管如此，编译器错误堆栈跟踪中有趣的部分是：
Caused by: javax.lang.model.element.UnknownElementException: Unknown element: "com.xxx.TestCls"

我觉得 org.hibernate.validator.ap.ConstraintValidationProcessor is invoking a visitor that is of type ConstraintAnnotationVisitor which itself extends AbstractElementVisitor which in turn extends ElementKindVisitor8. The latter is coming from the JDK and seems targeting Java 8 source, whereas records appear to be supported by AbstractElementVisitor14.
这让我怀疑这可能是不支持记录的 hibernate-validator ConstraintAnnotationVisitor 中的一个问题？也许在他们的 GitHub 回购协议中有一个更完整复制的问题会更有帮助。

public record TestCls(Party producer, Party client, Party server) {}

显然，按照评论中的建议升级 Maven 和 maven-compiler-plugin 的版本会更安全。尽管如此，编译器错误堆栈跟踪中有趣的部分是：
Caused by: javax.lang.model.element.UnknownElementException: Unknown element: "com.xxx.TestCls"

我觉得 org.hibernate.validator.ap.ConstraintValidationProcessor is invoking a visitor that is of type ConstraintAnnotationVisitor which itself extends AbstractElementVisitor which in turn extends ElementKindVisitor8. The latter is coming from the JDK and seems targeting Java 8 source, whereas records appear to be supported by AbstractElementVisitor14.
这让我怀疑这可能是不支持记录的 hibernate-validator ConstraintAnnotationVisitor 中的一个问题？也许在他们的 GitHub 回购协议中有一个更完整复制的问题会更有帮助。
