java - "Unresolved requirement: Import-Package: javax.ws.rs"在 Tomcat 上为 Liferay 部署 OSGi 模块时

Question

我目前正在 Maven 项目中使用 JAX-RS 和 Jackson 开发 REST API，但是当我尝试将它部署到服务器时遇到了一些问题。

显然它与 javax.ws.rs 包有关。也许 Liferay 或 Tomcat 正在使用它们自己的依赖项，这与我正在使用的版本冲突？

到目前为止，我已经尝试将这一行添加到我的 bnd.bnd 文件中:

Import-Package: javax.ws.rs; version="[1.1.0,2.0.0)"

我还尝试添加对我的 pom.xml 的依赖(我尝试了多个版本:2.0、2.0.1、2.1、2.1.1):

<dependency>
     <groupId>javax.ws.rs</groupId>
     <artifactId>javax.ws.rs-api</artifactId>
     <version>2.1.1</version>
</dependency>

我还尝试将那些 javax.ws.rs-api-2.X.X.jar

添加到项目的构建路径中

关于可能导致此问题的任何想法？我不知道我还应该尝试什么。

提前致谢。

与 Miroslav 的评论相反，我没有在提供的依赖项中找到 javax.ws.rs-api。因此，您通过依赖声明满足构建时依赖(对于编译器)。

生成的 Artifact (您自己的包)仍然对 javax.ws.rs-api-*.jar 具有运行时依赖性，您还需要部署它:只需将它放入您的 ${ liferay.home}/deploy 文件夹。现在它可用于任何依赖它的即将推出的包。

我怀疑 Miroslav 不久前就这样做了，现在可以在他的运行时中使用它了。或者我测试了错误的版本(我使用的是 DXP 7.2)或遗漏了一些东西。
