由于没有为Grab找到类加载器，Jenkins构建失败了

我是Jenkins，Groovy和Java的新手。我尝试为导入Java库的Jenkins创建一个测试共享库。但由于找不到classLoader，因此构建失败。我不明白这里发生了什么。任何人都可以指出我正确的方向找到解决方案。

package au.com.test.test

@Grapes([
    @Grab(group = 'com.amazonaws', module = 'aws-java-sdk', version =     '1.11.22'),
    @Grab(group = 'com.offbytwo.jenkins', module = 'jenkins-client', version = '0.3.7'),
    @GrabConfig(systemClassLoader=true)
])
import com.offbytwo.jenkins.client.JenkinsHttpClient
import com.amazonaws.* 
def prepTaskDefinition(File envStage) {
InputStream input = new FileInputStream(envStage)
BufferedReader reader = new BufferedReader( new InputStreamReader(input))
StringBuilder out = new StringBuilder()
String line
List<String> secrets = new ArrayList<>()
while ((line=reader.readLine() != null)) {
    if ( ! line.contains("#")) {
        if ( ! line.contains("\$")) {
            //secrets.add(line.subString(line.indexOf("{") + 1, line.indexOf("}")))
            secrets.add(line.substring(line.indexOf("{") + 1, line.indexOf("}")))
        }
        JenkinsHttpClient jenkinsHttpClient = new JenkinsHttpClient(new URI("https://test.company.com.au"))

        for (String secret : secrets) {
            String path = String.format("https://test.company.com.au/job/Domain/credentials/store/folder/test/_/credentials/%s", secret);
            jenkinsHttpClient.get(path)
        }
    }
}
reader.close()
return out

尽量不要使用

@GrabConfig(systemClassLoader=true)
来自groovydoc

的

  

public abstract boolean systemClassLoader

     

如果要在加载葡萄时使用系统类加载器，则设置为true。这通常仅在核心Java类需要引用抓取的类时才需要，例如对于使用DriverManager访问的数据库驱动程序。

看起来脚本不需要Java类来引用这些类。
