使用spring构建Web项目时如何修复MojoFailureException

最近我使用spring STS和roo 1.2.0.M1来构建一个web项目。我设置了 jpa 并创建了一个具有某些字段的实体，并为该实体创建了一个存储库和一个服务层，然后当我执行测试时，它给出了以下错误：

我在终端中运行 mvn 测试，出现以下错误：

我使用以下命令来构建项目：

jpa setup --database MYSQL --provider HIBERNATE --databaseName App --hostName localhost --password root --persistenceUnit app --transactionManager appTransactionManager --userName root
entity --class ~.app.domain.DomainObjBaseModel --mappedSuperclass --persistenceUnit app --transactionManager appTransactionManager

// After running the above command, I manually add the following stuff in DomainObjBaseModel, because I don't know how to customise the roo auto generate stuff
    @Id @GeneratedValue(generator="system-uuid")
    @GenericGenerator(name="system-uuid", strategy = "uuid")
    @Column(unique = true, name = "id", nullable = false, length=32)
    private String id;
// After this action, I continue run the following commands.

entity --class ~.app.domain.Application --extends com.crazysoft.web.app.domain.DomainObjBaseModel --persistenceUnit app --transactionManager appTransactionManager --serializable --testAutomatically
repository jpa --interface ~.app.repository.ApplicationRepository --entity ~.app.domain.Application
service --interface ~.app.service.ApplicationService --entity ~.app.domain.Application

这是maven插件的配置：

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>

完成上述工作后，然后运行perform tests通过STS roo shell，我得到了上述错误。

有谁知道为什么会出现这种异常？我做错了什么吗？以及如何修复它？

请帮我！

先感谢您！

一项或多项测试不起作用。

查看位于以下位置的文件：/Users/charlesli/Documents/workspace-spring/WebApplication/target/surefire-reports（通常较大的文件包含问题）

在那里您将找到测试结果以及已损坏的测试。该文件中包含的堆栈跟踪将指导您解决问题。

（顺便说一句：您也可以通过 JUnit 插件（Package explorer，右键单击，作为 JUnit 运行）在 eclipse 中运行测试，然后您将在 IDE 中看到堆栈跟踪，而无需在文件中搜索。）

我猜想，数据库连接不正确。但这只是一个猜测。
