Question

我有一个Eclipse / Maven项目：使用Maven的构建成功，但是Eclipse确实存在编译时错误，无法构建。我的Eclipse是Neon（4.6.3），我正在使用内置的Maven和JDK 1.8

您能帮我解决问题吗？

我的pom.xml：

Eclipse无法识别类中的以下导入：

import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.protocol.HttpContext;

Eclipse项目具有以下属性：

Answer 1

问题是，jar文件已损坏：

[ERROR]读取C：\ Users \ User.m2 \ repository \ org \ apache \ httpcomponents \ httpcore \ 4.4.11 \ httpcore-4.4.11.jar时出错；无效的LOC标头（错误的签名）

我通过替换依赖项解决了问题

<dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpcore</artifactId>
        <version>4.4.11</version>
    </dependency>

通过对早期版本的依赖：

4.4.10

Answer 2

你好

首先，您应该检查要在您的maven本地文件夹中包含apache jar文件。您本地的maven文件夹中有一些版本文件夹。但是没有jar文件。

OR

此行代码将添加到您的pom.xml文件中。

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.6</version>
</dependency>
