java - 如何修复 Javadoc 注释有解析错误，详细信息 : no viable alternative at input ' *' while parsing JAVADOC_TAG [NonEmptyAtClauseDescription]

Question

/**
* This method is used for ABC.
* @return
* @throw IOException when this exceptional condition occurs
*/

[Error]:line:4- Javadoc comment at column 0 has parse error. Details:no viable alternative at input ' *' while parsing JAVADOC_TAG[NonEmptyAtClauseDescription]

知道为什么我会在 Javadoc 的 @throw 行中收到此错误吗？如何解决这个问题？

Answer 1

如上所述，在返回标签中添加描述或将其完全删除以解决错误。

$ cat TestClass.java
public class TestClass {
    /**
    * This method is used for ABC.
    * @return desc
    * @throw IOException when this exceptional condition occurs
    */
    int method() throws IOException  {
        return 0; 
    }
}

$ cat TestConfig.xml
<?xml version="1.0"?>
<!DOCTYPE module PUBLIC
          "-//Puppy Crawl//DTD Check Configuration 1.3//EN"
          "https://checkstyle.org/dtds/configuration_1_3.dtd">

<module name="Checker">
    <property name="charset" value="UTF-8"/>

    <module name="TreeWalker">
        <module name="NonEmptyAtclauseDescriptionCheck" />
    </module>
</module>

$ java -jar checkstyle-9.0.1-all.jar -c TestConfig.xml TestClass.java
