我在运行 mvn clean verify -P P1 时得到这个奇怪的堆栈跟踪

由于字符串变量中的垃圾以及日志中偶尔出现的IndexOutOfBoundsException / ConcurrentModificationException，这似乎是一个并发问题。

【解决方案1】：

这个 GitHub 问题 - [#6254] Maven-failsafe-plugin fails to execute integration tests - 以及相关讨论帮助我解决了我的问题。

这是一个错误。事实证明，较新的 Failsafe 插件版本（2.19.0 及更高版本）不适用于 Spring Boot 1.4（或更高版本）。解决方法是将 maven-failsafe-plugin 降级到 2.18.1。这是更新后的 pom.xml：

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <!-- I don't specify version at all (Spring Boot can autoconfigure plugin version) -->
        <executions>
            <execution>
                <!-- changed <id> to <phase>, but I don't know whether it's important or not. -->
                <phase>integration-test</phase>
                <!-- ... no changes here: the same as in the question ... -->
            </execution>
        </executions>
    </plugin>
</plugins>

【讨论】：

基本上，较新的版本针对 JAR 进行测试，而在 v2.18.1 之前，故障安全使用 test-class。
这个配置根本不运行集成测试。这不是一个正确的答案。
@burtsevyg，你如何运行集成测试？试试mvn verify 命令。
我运行mvn deploy。
@burtsevyg mvn deploy 也应该可以工作。尝试mvn verify 进行比较，看看它是否运行您的集成测试。你遵循命名约定吗？默认情况下，Failsafe 插件运行名为 */IT.java、**/*IT.java 和 **/*ITCase.java 的测试类。

【解决方案2】：

我遵循了这里提出的解决方案： https://github.com/spring-projects/spring-boot/issues/6254#issuecomment-307151464

目前，我有故障安全插件 2.22.0，我可以通过显式配置 classesDirectory 属性来使用此版本而不是降级：

<classesDirectory>${project.build.outputDirectory}</classesDirectory>

例子：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-failsafe-plugin</artifactId>
  <version>2.22.0</version>
  <configuration>  
     ...                 
     <classesDirectory>${project.build.outputDirectory}</classesDirectory>
     ...
  </configuration>
  <executions>
     <execution>
        <goals>
           <goal>integration-test</goal>
           <goal>verify</goal>
        </goals>
     </execution>
  </executions>
</plugin>

解决方法的另一种变体稍后在同一个 Github 问题线程中描述：https://github.com/spring-projects/spring-boot/issues/6254#issuecomment-343470070

<classesDirectory>${project.build.directory}/${artifactId}.jar.original</classesDirectory>

注意 (2020-02-27)：maven-failsafe-plugin 版本 3.0.0-M4 仍然需要这些解决方法 :-(

我的 testng 类有 LoginPageTest.java，我删除了 .java 并且工作得非常好。 :)

<classes>
  <class name="com.qa.Backend.tests.LoginPageTest"/>
</classes>
