我的 Eclipse 工作区中有两个 Android 项目。

主项目称为 Hello，另一个用作库引用的 android 项目称为 HelloLibrary。

我通过右键单击 Hello 项目并将 HelloLibrary 添加为库项目，在 Eclipse 构建路径中添加了 HelloLibrary 项目。

Eclipse 设法找到、编译和构建现在使用 HelloLibrary 代码的 Hello 项目，但是在 Maven 上，当我尝试使用以下命令构建和运行测试时，它找不到 HelloLibrary 项目：

mvn clean test -e

全栈跟踪如下：

有什么方法可以将 HelloLibrary 添加到 maven 构建路径中，还是我还需要为 HelloLibrary 创建一个 maven 脚本工件？

两者都是 Android 项目。

编辑。我将此添加到 Hello pom 文件中

<dependency>
            <groupId>com.example.hellolibrary</groupId>
            <artifactId>HelloLibrary</artifactId>
            <version>1.0.0-SNAPSHOT</version>
            <type>apklib</type>
            <scope>compile</scope>
        </dependency>

由于找不到位于 HelloLibrary 项目中的 Lib 类对象，测试失败

这是我的测试课

/** * 测试类 */ @RunWith(RobolectricTestRunner.class) public class TestFullscreenActivity {

private String stringOne = "hello";
private String stringTwo = "world";

@Test
public void test() {

    Assert.assertEquals(true, false);

}

@Test
public void testTwo() {

    Lib lib = new Lib();
    Assert.assertEquals(stringOne+stringTwo, lib.combineText(stringOne, stringTwo));

}

@Test
public void testThree() {

    Assert.assertEquals(true, true);

}

}

这是位于 HelloLibrary 项目中的 Lib 类

package com.example.hellolibrary;

/**
 * Test lib with some random methods
 * @author
 *
 */
public class Lib {

    public String combineText(String stringOne, String stringTwo){

        String result = "";

        result = stringOne + stringTwo;

        return result;

    }

}

这是用于 HelloLibrary 项目的 pom 文件的上半部分

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.example.hellolibrary</groupId>
    <artifactId>HelloLibrary</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>apklib</packaging>
    <name>HelloLibrary</name>

谢谢

在 maven 依赖项中使用非 maven 项目有一个解决方法，我们不应该使用它，但是当我们没有选择时，使用“系统”范围：

<dependency>

  <groupId>org.yourjar</groupId>
  <artifactId>yourjar</artifactId>
  <version>0.1</version>
  <scope>system</scope>
  <systemPath>${project.basedir}/lib/yourjar.jar</systemPath>

</dependency>
