在 Maven 构建中测试 testng 之前运行 antrun 插件

Question

当我运行项目的构建时，在运行测试之前，我需要下载并解压缩 chromedriver。

<dependencies>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>

</dependencies>

            <version>1.8</version>

                <execution>
                    <phase>package</phase>
                    <configuration>
                        <target>
                            <get src="https://chromedriver.storage.googleapis.com/2.26/chromedriver_win32.zip"
                                 dest="${project.basedir}"
                                 verbose="false"
                                 usetimestamp="true" />
                            <unzip src="${project.basedir}/chromedriver_win32.zip" dest="${project.basedir}/drivers/" />
                            <delete file="${project.basedir}/chromedriver_win32.zip" />
                        </target>
                    </configuration>
                    <goals>
                        <goal>run</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <executions>
                <execution>
                    <phase>test</phase>
                        <goals>
                            <goal>test</goal>
                        </goals>
                            <configuration>
                                <suiteXmlFiles>
                                    <suiteXmlFile>src/test/resources/testng.xml</suiteXmlFile>
                                </suiteXmlFiles>
                            </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

要下载我正在使用 antrun 插件，但是，即使稍后在 pom.xml 中声明了surefire插件，正如我在other questions 中看到的那样，稍后也运行测试，构建之前没有下载驱动程序。

我做错了什么？任何帮助将不胜感激。

您需要了解 Maven 生命周期（请参阅 Introduction to the Build Lifecycle），它规定了 maven 处理您的构建的顺序。

在您的情况下，您为执行 maven-antrun-plugin 指定了 <phase>package</phase>，它位于 test 之后。

我会为您的用例使用类似 <phase>process-test-resources</phase> 的内容。
