将eclipse项目库添加​​到maven构建路径？

Question

我的eclipse工作区里有两个Android项目。

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

我已经在eclipse构建路径中添加了HelloLibrary项目，方法是右键单击Hello项目并将HelloLibrary添加为库项目。

Eclipse设法查找，编译和构建现在使用HelloLibrary代码的Hello项目，但是当我尝试使用以下代码构建和运行测试时，它无法找到HelloLibrary项目：

mvn clean test -e

完整堆栈跟踪如下：

我可以将HelloLibrary添加到maven构建路径中，还是需要为HelloLibrary创建maven脚本工件？

两者都是Android项目。

编辑。我将此添加到Hello pom文件

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

由于未找到位于HelloLibrary项目中的Lib类对象

，

并且测试失败

这是我的测试类

/ **  *考试班  * / @RunWith（RobolectricTestRunner.class） 公共类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;

    }

}

以下是用于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>

在maven依赖项中使用非maven项目有一种解决方法，我们不应该使用它，但是当我们没有选择时，请使用“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>
