Maven don'；t执行junit测试

我正在尝试测试此项目： 但是maven说：

$ mvn clean install

警告是什么？为什么maven完全跳过了测试阶段

这项工作的最终目的是测试电子邮件jenkins功能，但现在我被这个问题阻止了

谢谢

总结 您需要将

GreetingTests.java

重命名为

GreetingTest.java

，或者更新

maven-surefire插件。更新surefire插件可以为用户提供更好的模式。您可以在项目的父POM
/POM.xml
中声明它：

<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <!-- ... -->

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>2.20.1</version>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>
</project>

您需要将测试重命名为
GreetingTests.java
为
GreetingTest.java
。因为
surefire插件：2.12.4
无法识别模式
*Tests.java
，如文档所述：

默认情况下，插件将自动包含具有以下通配符模式的所有测试类：


“***/Test*.java”
-包括其所有子目录和所有java
以“Test”开头的文件名

“***Test.java”
-包括其所有子目录和所有java
以“Test”结尾的文件名

“***TestCase.java”
-包括其所有子目录和所有java
以“TestCase”结尾的文件名


使用选项
-X
运行Maven以查看调试消息。出现警告是因为库尚未升级到Java 9
