构建测试
我们在
“项目创建”一章中学到的是如何使用Maven创建Java应用程序。现在,我们将看到如何构建和测试应用程序。转到创建Java应用程序的C:/ MVN目录。打开ConsumerBanking文件夹。您将看到带有以下内容的pom.xml文件。
<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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.companyname.projectgroup</groupId>
<artifactId>project</artifactId>
<version>1.0</version>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
</dependency>
</dependencies>
</project>
在这里您可以看到,Maven已经添加了Junit作为测试框架。默认情况下,Maven 在其默认目录结构中添加了源文件App.java和测试文件AppTest.java,如上一章所述。让我们打开命令控制台,进入C:\MVN\consumerBanking目录并执行以下mvn命令。
C:\MVN\consumerBanking>mvn clean package
Maven将开始构建该项目。

您已经构建了项目并创建了最终的jar文件,以下是关键的学习概念
- 我们给maven两个目标,首先清理目标目录(clean),然后将项目构建输出打包为jar(package)。
- 打包的jar可在ConsumerBanking\target文件夹中作为ConsumerBanking-1.0-SNAPSHOT.jar提供。
- 测试报告位于ConsumerBanking\target\surefire-reports文件夹中。
- Maven编译源代码文件,然后测试源代码文件。
- 然后,Maven运行测试用例。
- 最后,Maven创建包。
现在打开命令控制台,转到C:\MVN\consumerBanking\target\classes目录,然后执行以下Java命令。
>java com.companyname.bank.App
您将看到如下结果
