### Question:
AbstractCodeScanAdapterConfigBuilder extends AbstractAdapterConfigBuilder<B,C> { @SuppressWarnings("unchecked") public final B setFileSystemSourceFolders(Set<String> sourceFolders) { this.sourceFolders=sourceFolders; return (B) this; }  @SuppressWarnings("unchecked") final B setFileSystemSourceFolders(Set<String> sourceFolders);  }### Answer:
@Test public void settingSourceFoldersResultsInTargetString() { TestCodeScanAdapterConfig x = new TestAbstractCodeScanAdapterConfigBuilder() .setFileSystemSourceFolders(new LinkedHashSet<>(Arrays.asList("src/java/", "src/groovy"))).build(); assertEquals("src/java/;src/groovy", x.getTargetAsString()); }
