Я хочу использовать Apache-POI в своем коде, но получаю сообщение об ошибке The import org.apache.poi cannot be resolved
в операторе импорта import org.apache.poi.xssf.usermodel.XSSFWorkbook;
Я новичок с недавно настроенным кодом Visual Studiov1.30.2, Maven 3.6.0, Java JRE 1.8.0_201.
Я активировал следующие расширения: отладчик для Java, средство просмотра зависимостей Java 0.16.0, пакет расширений Java 0.3.0, Java Java 0.5.0тестовый прогон, 0.14.0 Поддержка языков для Java (TM), 0.37.0 Maven для Java, 0.14.0
Я ввел эти операторы в pom.xml в разделе зависимостей:
<!-- https://mvnrepository.com/artifact/org.apache.poi/poi-->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.0.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml -->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>4.0.1</version>
</dependency>
Я также пытался использовать другие версии POI, например, 3.10-FINAL.
Я слишком новичок в Java, Maven и VSCode, чтобы быть уверенным, что я включил всю необходимую информацию, чтобы указать нарешение.Пожалуйста, помогите мне:)
Я запустил mvn compile
, с таким результатом:
