我正在使用Intellij Idea，当我开始生成JavaDocs（通过Tools - ＆gt; Generate JavaDoc）时，我会抛出IllegealArgumentException而没有关于出错的信息。
即使没有JavaDoc注释，在使用模块中的每个单独文件进行测试时也会发生这种情况。
以下是我获得的堆栈跟踪示例：

据我所知，它并没有真正告诉我有关实际错误的信息。这是我尝试为以下内容生成JavaDocs的示例文件：
package Network;
public class NetworkTags {
public static final String OPEN_TAG = "<";
public static final String CLOSE_TAG = "/>";
public static final String NET_OPEN_TAG = "<NET>";
public static final String NET_CLOSE_TAG = "</NET>";
public static final String VERTEX_TAG = "VERTEX";
public static final String EDGE_TAG = "EDGE";
public static final String REL_TAG = "REL";
public static final String TYPE_TAG = "TYPE";
public static final String COST_TAG = "COST";
public static final String NAME_TAG = "NAME";
public static final String SOURCE_TAG = "SOURCE";
public static final String TARGET_TAG = "TARGET";
public static final String FROM_TAG = "FROM";
public static final String TO_TAG = "TO";
}
使用Java 8和IntelliJ IDEA 2016.1.1
答案 0 :(得分：5)
我遇到了同样的问题。 你要删除CLASSPATH环境变量。
答案 1 :(得分：2)
如果您的类路径包含％init。
，则会出现此问题
