我的DSL作业生成器出现问题：

我正在运行一个访问gitswarm API的DSL作业生成器，获取有关可用项目及其分支的信息，并创建Jenkins作业。

与gitswarm api的交互是通过Client类 - 我的gitswarm API客户端完成的。

Generator.groovy：

class Generator {

SystemCredentialsProvider systemCredentialsProvider = (SystemCredentialsProvider) Jenkins.instance.getExtensionList('com.cloudbees.plugins.credentials.SystemCredentialsProvider')[0]
CredentialsStore credentialsStore = (CredentialsStore) systemCredentialsProvider.getStore()
Domain domain = Domain.global()
List<Credentials> credentials = credentialsStore.getCredentials(domain)

Client client

Generator(String tokenId="gitswarm_token") {
    credentials.each { Credentials credentials ->
        if(credentials.getId() == tokenId) {
            GitLabApiTokenImpl token = (GitLabApiTokenImpl) credentials //line 28
            client = new Client(apiToken: token.getApiToken().getPlainText())
        }
    }
}

boolean generateJobs(DslFactory factory) {
    ArrayList<Project> supportedProjects = client.getSupportedProjects()
    supportedProjects.each { supportedProject ->
        handleProject(supportedProject, factory)
    }
    return true
}
}

Jenkins正在运行这个DSL种子作业：

import com.blue.devops.generator.Generator
new Generator().generateJobs(this)

请帮忙

Job DSL类加载器不支持访问其他插件提供的类。因此，您无法从其他插件导入类，也无法将对象强制转换为该类。

但Groovy是一种动态语言。您不需要将对象强制转换为特定类，以便能够访问其成员。 Groovy将在运行时解决这个问题。以下示例显示如何使用插件中的任何类来获取API令牌。

def systemCredentialsProvider = Jenkins.instance.getExtensionList('com.cloudbees.plugins.credentials.SystemCredentialsProvider')[0]
def credentials = systemCredentialsProvider.credentials
def gitlabCredentials = credentials.find { it.id == 'test' }
def apiToken = gitlabCredentials.apiToken.plainText

无法在Jenkins作业生成器
