英文:
@NotNull Deprecated in Antlr 4.6+ What to use instead?
问题
我正在使用 Antlr 4.8 构建解析器，而 @NotNull 注解被标记为已弃用：
org.antlr.v4.runtime.misc
注解类型 NotNull
已弃用。
此仅用于与 4.5 版本向后兼容。它将在 4.6+ 版本中被移除。
我已经搜索过，但没有找到有关将替换此注解的任何文档。显然它在 4.6+ 版本中并未消失，但我希望在迁移到 Antlr 的新版本时避免问题。
是否有人知道是否有此注解的替代品？
英文:
I'm building a parser using Antlr 4.8, and the @NotNull annotation is marked as deprecated:
org.antlr.v4.runtime.misc
Annotation Type NotNull
Deprecated.
THIS IS HERE FOR BACKWARD COMPATIBILITY WITH 4.5 ONLY. It will disappear in 4.6+
I have searched but haven't found any documentation on what would replace this annotation. Obviously it hasn't disappeared in 4.6+, but I'd like to avoid issues as I move to new versions of Antlr.
Anyone know if there is a replacement for this annotation?

你可以通过以下方式使用 @NonNull：
import org.checkerframework.checker.nullness.qual.NonNull;
如果你正在使用 Maven，以下是导入依赖的代码：
<dependency>
<groupId>org.checkerframework</groupId>
<artifactId>checker-qual</artifactId>
<version>2.10.0</version>
</dependency>
英文:
You can use @NonNull via
import org.checkerframework.checker.nullness.qual.NonNull;
Here's the import if you're using Maven:
<dependency>
<groupId>org.checkerframework</groupId>
<artifactId>checker-qual</artifactId>
<version>2.10.0</version>
</dependency>

因为你说你的项目正在使用 Antler 4.8，所以你会想要将你所使用的 antlr4-maven-plugin 版本设置为 4.8。
将它设置为 4.6 也消除了错误，但我认为将 antlr 插件和运行时版本保持一致是有道理的。
英文:
Since you say you are using Antler 4.8 for your project, you'll want to set the version of the antlr4-maven-plugin that you are using to version 4.8.
Setting it to 4.6 also got rid of the error, but really I think it makes sense to keep the antlr plugin and runtime at the same version.
