java - JClouds-Chef BootstrapConfig Builder MissingMethodException

Question

请注意:虽然这个问题涉及JClouds-Chef这里有库和 Groovy，我认为这本质上是一个 Java API 问题。

在 JClouds-Chef 1.7.3 上:

List<String> runlist = new RunListBuilder().addRole("typicalapp").build();

ArrayList<String> runList2 = new ArrayList<String>();
for(String item : runlist) {
    runList2.add(item);
}

System.out.println("runList2 is of type: " + runList2.getClass().getName());

BootstrapConfig bootstrapConfig = BootstrapConfig.builder().runlist(runList2).build();

产生以下输出/异常:

runList2 is of type: java.util.ArrayList
Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: org.jclouds.chef.domain.BootstrapConfig$Builder.runlist() is applicable for argument types: (java.util.ArrayList) values: [[role[typicalapp]]]
Possible solutions: runList(java.lang.Iterable), build(), split(groovy.lang.Closure)

我很确定此版本的代码 BootstrapConfig#Builder is here 。据我所知，ArrayList 扩展了Iterable，所以我看不到这里发生了什么。

您正在使用 runlist 而不是 runList
