[keycloak-user] Keycloak Admin Client dependencies for Keycloak 5.0.0?

[Jody H]

Hi,

I have looked around on Google for a while now but I can't seem to figure
out my problem. I mostly used the Gist from Github here to get started:
https://gist.github.com/thomasdarimont/43689aefb37540624e35
After things were not really working out, I tried some other stuff that you
can find below:
I am trying to use the Keycloak admin client in Java, version 5.0.0.

My POM contains the following:

<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>

<keycloak.version>5.0.0</keycloak.version>
<resteasy.version>3.1.3.Final</resteasy.version>
<jackson.version>2.9.8</jackson.version>
</properties>

<dependencies>
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-admin-client</artifactId>
<version>${keycloak.version}</version>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-client</artifactId>
<version>${resteasy.version}</version>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jackson2-provider</artifactId>

<artifactId>jackson-core</artifactId>

</dependency>
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>${jackson.version}</version>
</dependency>
</dependencies>

When I add the following code, building the keycloak client fails:
Keycloak keycloak =
KeycloakBuilder.builder().serverUrl("localhost:8080/auth").realm("master")
.username("admin").password("admin").clientId("admin-cli").build();

System.out.println(keycloak.serverInfo().getInfo().toString());

Produces the following exception:
 java -jar .\keycloak-admin-0.0.1-SNAPSHOT.jar
Exception in thread "main" java.lang.IllegalArgumentException:

When using the Keycloak.getInstance method, I get another exception:
Keycloak keycloak = Keycloak.getInstance("http://localhost:8080/auth",
"master", "admin", "admin", "admin-cli");

Produces exception:

Can someone share insight on how to use the keycloak admin client library
in the most recent version? Which dependencies do I need inside of my pom?

Thanks!
