我遇到了這個錯誤：

org.glassfish.jersey.containers：jersey-container-grizzly2-http：jar的'dependencies.dependency.version'已丟失

幫我解決問題。

Answer 1

您需要在依賴項聲明中添加版本信息：

例如：

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-grizzly2-http</artifactId>
    <version>2.21</version>
</dependency>

Answer 2

我刪除這些評論：

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-moxy</artifactId>
</dependency>

然后就可以了。 這是示例源代碼中的缺陷。
