Keycloak getAccessToken在Java Eclipse / Maven项目中有效，但抛出通过命令行运行的ProcessingException

问题描述 投票：0回答：1

当在Eclipse环境中运行时，我在Eclipse中的Maven项目从我们的密钥斗篷服务器检索访问令牌。当我编译包含所有依赖项的胖jar时，在同一JDK / JRE（1.8）上运行的同一代码将引发ProcessingException。让我陷入循环的事实是，它可以通过Eclipse（瘦JAR）在同一台计算机上运行，​​而不是通过命令行（胖JAR）在同一台计算机上运行。两种环境都使用相同的Java安装和相同的库。 

javax.ws.rs.ProcessingException: RESTEASY004655: Unable to invoke request: javax.ws.rs.ProcessingException: RESTEASY003215: could not find writer for content-type application/x-www-form-urlencoded type: javax.ws.rs.core.Form$1
        at org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine.invoke(ApacheHttpClient4Engine.java:325)

我已经阅读了关于stackoverflow的类似问题，并在网上搜索了异常以及RESTEASY代码。我尝试了以下更改，但没有更改行为...

  1. 使用jboss ApacheHttpClient4Engine和ResteasyClientBuilder
  2. 密钥斗篷版本：6.0.1、7.0.1、8.0.1

代码环境：

  • OS：Windows 10
  • Eclipse RCP版本2019-12
  • Windows 10命令行
  • JDK 1.8.0_231（用于命令行和Eclipse的二进制文件和库的相同安装）

下面是代码的相关部分pom.xml和完整的堆栈跟踪。请让我知道更多细节是否有帮助。谢谢！

          if (!requireValidToken) return;

            keycloak = KeycloakBuilder.builder()
                    .serverUrl(deployment.getAuthServerBaseUrl())
                    .realm(deployment.getRealm())
                    .username(username).password(passwd)
                    .clientId(deployment.getResourceName())
                    .resteasyClient(new ResteasyClientBuilder().build()).build();

            System.out.println("CODE ALWAYS THROWS AN EXCEPTION AT THE NEXT LINE");
            AccessTokenResponse tokenResponse = keycloak.tokenManager().getAccessToken();   
            System.out.println("CODE ALWAYS THROWS AN EXCEPTION BEFORE THIS LINE");
            setAccessToken(tokenResponse.getToken());
            verifyToken(tokenResponse.getToken(), null, null, null);                    

        } catch (Exception e) {         
        e.printStackTrace();

Kinda晚了，但是对于Maven项目，请看这里：resteasy providers missing after mvn package

对于Gradle项目，需要使用Gradle Shadow Plugin。

shadowJar {
    mergeServiceFiles()

    append 'META-INF/services/javax.ws.rs.ext.Providers'
}
