编译错误，包javax.ws.rs不存在，依赖项未从maven解析

Question

我已经提到了pom文件中的依赖库，库系统路径也存在，但是在使用maven洁净安装-e -X进行编译时，它会引发错误，说明包不存在。

Answer 1

您需要在POM中包含Java依赖项，并包含一个provided作用域(也就是，这些文件最终将由应用服务器提供，但同时我需要它们进行编译)。

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-web-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

Answer 2

在系统更新之后，当NetBeans更改字体和图形用户界面时，我遇到了更多类似的问题。我通过在Java EE 6 API Library IDE中添加NetBeans来解决这个问题

myProject->Properties->Libraries->Add Library

Answer 3

“感知”回答的依赖也是必要的，但对我来说也是不够的。还需要下列依赖性：

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

https://mvnrepository.com/artifact/javax.ws.rs/javax.ws.rs-api/2.0
