2. Plugin Goal
2.插件目标
The verifier plugin has only one goal – verify. This goal verifies the existence or non-existence of files and directories, optionally checking file content against a regular expression.
verifier插件只有一个目标 – verify。这个目标是验证文件和目录的存在与否，可以选择根据正则表达式检查文件内容。
Despite its name, the verify goal is bound to the integration-test phase by default rather than the verify phase.
尽管它的名字是verify，但verify目标默认与integration-test阶段绑定，而不是verify阶段。
3. Configuration
3.配置
The verifier plugin is triggered only if it’s explicitly added to the pom.xml:
只有当verifier插件被明确添加到pom.xml时才会被触发。
<plugin>
<artifactId>maven-verifier-plugin</artifactId>
<version>1.1</version>
<configuration>
<verificationFile>input-resources/verifications.xml</verificationFile>
</configuration>
<executions>
<execution>
<goals>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>This link shows the newest version of the plugin.

The default location of the verification file is src/test/verifier/verifications.xml. We must set a value for the verificationFile parameter if we want to use another file.
验证文件的默认位置是src/test/verifier/verifications.xml。如果我们想使用其他文件，我们必须为verificationFile参数设置一个值。
Here’s the content of the verification file shown in the given configuration:
下面是给定配置中显示的验证文件的内容。
<verifications
xmlns="http://maven.apache.org/verifications/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/verifications/1.0.0
http://maven.apache.org/xsd/verifications-1.0.0.xsd">
<files>
<file>
<location>input-resources/baeldung.txt</location>
<contains>Welcome</contains>
</file>
</files>
</verifications>This verification file confirms that a file named input-resources/baeldung.txt exists and that it contains the word Welcome. We’ve already added such a file before, thus the goal execution succeeds.
这个验证文件确认了一个名为input-resources/baeldung.txt的文件存在，并且它包含Welcome这个词。我们之前已经添加了这样一个文件，因此目标执行成功了。
