Maven Failsafe 插件找不到类

Question

我正在处理的项目有几个模块，其中一个模块是integration_test，对所有其他模块进行集成测试。这对我来说是一个奇怪的架构，我不确定我是否正确处理了这种情况。

我们还没有持续集成，现在我们正在从 Eclipse 运行套件测试，但我们想从持续集成服务器运行它。我一直在努力更新我们的 POM 以从命令行执行它。我将在下面包含一个示例项目，因为在这里粘贴我认为还不够的类。

我遵循了 Maven Failsafe 插件文档，但是当我执行 mvn clean verify -P integration-test 时，我得到了 Cannot find class in classpath: TestApiMain

我认为这是因为试图在编译之前运行该类，但我不知道在所有其他模块实际编译后如何运行集成测试。我还想实现 Jacoco 以进行测试覆盖。阅读以下实施 Jacoco 的指南，我想我已经接近了：

执行mvn clean verify -P integration-test时出现异常：

Answer 1

您在 build/plugins 部分的父 pom 中定义了插件 failsafe。这意味着在阶段integration-test 中的每个模块，包括父模块，都必须调用failsafe(TestApiMain.class)。

它不起作用，因为TestApiMain 是在最后一个模块integration_test 中定义的

您应该将failsafe 定义移动到integration_test/pom.xml 到build/plugins 部分

对于阅读此内容且项目配置正确但仍找不到类的任何人，请查看以下内容是否适用。

升级到 3.0.0-M5 时，此插件可能无法从传递依赖项中找到类。除了回滚到 3.0.0-M4 之外，一个简单的修复方法是将 classesDirectory 添加到您的插件配置中

<pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-failsafe-plugin</artifactId>
                <configuration>
                    <classesDirectory>${project.build.outputDirectory}</classesDirectory>
                </configuration>
            </plugin>
        </plugins>
</pluginManagement>
