运行 JUnit 配置时，下面的断言失败。

String dirName = System.getProperty("dataDir");
Assert.assertNull(dirName);

pom.xml中描述的参数dataDir

<systemProperties>
                    <property>
                        <name>dataDir</name>
                        <value>src/main/resources/data</value>
                    </property>
</systemProperties>

【解决方案1】：

maven-surefire-plugin 已弃用系统属性构造 http://maven.apache.org/surefire/maven-surefire-plugin/examples/system-properties.html

添加属性的正确方法是

<systemPropertyVariables>
                <propertyName>propertyValue</propertyName>
                <buildDirectory>${project.build.directory}</buildDirectory>
    </systemPropertyVariables>

试试这个：

<build>
<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19</version>
    <configuration>
      <systemPropertyVariables>
        <propertyName>dataDir</propertyName>
        <buildDirectory>src/main/resources/data</buildDirectory>
       </systemPropertyVariables>
    </configuration>
  </plugin>
</plugins>

如果你需要复制库，你可以这样做

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>prepare-package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/project/WEB-INF/lib</outputDirectory>
                        <overWriteReleases>false</overWriteReleases>
                        <overWriteSnapshots>false</overWriteSnapshots>
                        <overWriteIfNewer>true</overWriteIfNewer>
                    </configuration>
                </execution>
            </executions>
        </plugin>
