Question

以下依赖项已添加到我的pom.xml文件中，但Java无法解析导入的类。

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.1.2</version>
    <type>jar</type>
</dependency>

httpcomponents jar存在于我的本地Maven存储库中（在~/.m2/repository/org/apache/httpcomponents中）但我可以在Eclipse中看到它没有出现在Maven依赖项中。

通常的错误仍然存在。

The import org.apache.http.entity.mime cannot be resolved

我认为我犯了一些愚蠢的错误/忽视某些事情（例如，我是否需要在pom.xml文件中添加第三方存储库？）

修改

完整的pom.xml文件如下。

Answer 1

如果二进制文件出现在本地存储库中，则无需执行任何其他操作。只需让m2eclipse更新您的项目配置（右键单击您的项目 - ＆gt; Maven - ＆gt;更新项目......）它应该解决您的依赖

Answer 2

尝试使用

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.3.2</version>
</dependency>

代替。

（从http://search.maven.org/#artifactdetails%7Corg.apache.httpcomponents%7Chttpclient%7C4.3.2%7Cjar复制）

Answer 3

显然我一直在添加错误的依赖项。这是正确的：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpmime</artifactId>
    <version>4.0.1</version>
</dependency>

无法解决maven中的httpcomponent依赖关系
