请注意:尽管此问题涉及JClouds-Chef库和Groovy,但我认为这是Java API的核心问题。
在JClouds-Chef 1.7.3上,这里:
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
BootstrapConfig#Builder
is here版本的代码。据我所知,ArrayList
扩展了Iterable
,所以我看不到这里发生了什么。 最佳答案
您正在使用runlist
而不是runList
