Add members to JavaPoet

Question

I tried to create TestSuite in JavaPoet api. I have List with my junit classes in testClasses, so i want to add member annotation but addmember allow us to add only one object at time, so how i can add All list?

.addAnnotation(AnnotationSpec.builder(SuiteClasses.class)
.addMember("value", "$T.class", testClasses.toArray()).build())

Try extracting a variable for the builder.

AnnotationSpec.Builder ab = AnnotationSpec.builder(SuiteClasses.class);
for (String s : strings) {
  ab.addMember(s, "$S", lookup(s));
}
AnnotationSpec annotation = ab.build();
