Keycloak 在KeyClope扩展中实现AbstractOAuth2IdentityProvider时发生NoClassDefFoundError

我尝试为KeyClope实现一个自定义OAuth社交登录提供程序。我的蓝图是keybeapt代码中的实现

这是我的pom.xml：

<dependencies>
    <dependency>
        <groupId>org.keycloak</groupId>
        <artifactId>keycloak-core</artifactId>
        <version>${keycloak.version}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.keycloak</groupId>
        <artifactId>keycloak-server-spi</artifactId>
        <version>${keycloak.version}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.keycloak</groupId>
        <artifactId>keycloak-server-spi-private</artifactId>
        <version>${keycloak.version}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.keycloak</groupId>
        <artifactId>keycloak-services</artifactId>
        <version>${keycloak.version}</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

那么，我怎样才能解决这个问题呢？ 如何使org/keydepot/broker/oidc/AbstractOAuth2IdentityProvider可用于我的keydeport模块

我没有定义module.xml，因为我正在使用。社交SPI是一种带钥匙斗篷的私人SPI。甚至可以在自定义扩展中使用私有SPI吗
