Ошибка компиляции на maven

Question

Работа над проектом maven. Я пытаюсь построить с помощью maven, но я получаю следующую ошибку! Я работаю на затмение с использованием JDK 8.

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile)

Я также попытался выше решение, но все же я получаю сообщение об ошибке!

Answer 1

Проверьте с этим ниже зависимость, если она присутствует или нет?

<dependency> 
<groupId>javax.ws.rs</groupId> 
<artifactId>javax.ws.rs-api</artifactId> 
<version>2.0-m01</version> 
</dependency> 

Answer 2

Возможно, вам не хватает dependency on javax.ws.rs. Убедитесь, что у вас есть это в вашем pom.xml и повторите попытку.

Независимо от того, какой учебник вы используете, также должна быть информация о этих зависимостях.
