使用系统属性

有两种方法可以将系统属性列表添加到 Failsafe：

系统属性变量

此配置是已弃用的systemProperies的替换。它可以从 Maven 的属性中接受任何可以转换为字符串值的值

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.6</version>
        <configuration>
          <systemPropertyVariables>
            <propertyName>propertyValue</propertyName>
            <buildDirectory>${project.build.directory}</buildDirectory>
            [...]
          </systemPropertyVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

系统属性（已弃用）

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.6</version>
        <configuration>
          <systemProperties>
            <property>
              <name>propertyName</name>
              <value>propertyValue</value>
            </property>
            [...]
          </systemProperties>
        </configuration>
        <executions>
          <execution>
            <id>integration-test</id>
            <goals>
              <goal>integration-test</goal>
            </goals>
          </execution>
          <execution>
            <id>verify</id>
            <goals>
              <goal>verify</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

请注意，字符串值属性只能作为系统属性传递。任何传递任何其他 Maven 变量类型（即List或URL变量）的尝试都将导致变量表达式按字面意思传递（未计算）。所以有一个下面的例子：

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.6</version>
        <configuration>
          <systemProperties>
            <property>
              <name>buildDir</name>
              <value>${project.build.outputDirectory}</value>
            </property>
          </systemProperties>
        </configuration>
        <executions>
          <execution>
            <id>integration-test</id>
            <goals>
              <goal>integration-test</goal>
            </goals>
          </execution>
          <execution>
            <id>verify</id>
            <goals>
              <goal>verify</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

将直接传递${project.build.outputDirectory}因为该表达式的值是File，而不是String。
