Dropwizard 示例包编译错误

Question

我对 Java 及其工具完全陌生，我想使用 Dropwizard 框架。我在其 repository 中找到了一个示例，但是我无法运行它。

如 README.md 中所述，我需要运行 mvn package。但是，据我了解，Maven 尝试运行集成测试但抛出异常。堆栈跟踪是这样的：

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 5.975 sec << FAILURE! - in com.example.helloworld.IntegrationTest
com.example.helloworld.IntegrationTest  Time elapsed: 5.974 sec  <<< ERROR!

我认为它在区域设置方面存在一些问题，因为我的操作系统是 OS X 10.11 Turkish，其中我们将字符串大写 'i' 到 'İ'，而不是 'I'.

我正在使用 IntelliJ IDEA，你能告诉我如何为接受测试的人更改当前语言环境吗（我不知道它是 JVM 或 Maven 或其他...)?

根据要求，我的 migrations.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>

<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
         http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.1.xsd">

    <changeSet id="1" author="codahale">
        <createTable tableName="people">
            <column name="id" type="bigint" autoIncrement="true">
                <constraints primaryKey="true" nullable="false"/>
            </column>
            <column name="fullName" type="varchar(255)">
            <constraints nullable="false"/>
            </column>
            <column name="jobTitle" type="varchar(255)"/>
        </createTable>
    </changeSet>
</databaseChangeLog>

这应该是由您的 Java 虚拟机 (JVM) 的区域设置引起的。

只需打开终端或控制台（Windows）并运行以下命令，即可将语言环境更改为英语。

set JAVA_ARGS=-Duser.language=en -Duser.region=US %JAVA_ARGS%

要实现自动化，您可能需要在终端启动脚本中导出环境变量，例如 .bash_profile.
