Run antrun plugin before suit tests of testng in maven build

Question

When I run the build of my project, before running the tests, I need to download and unzip the chromedriver.

                            <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>

To download I'm using the antrun plugin, but, even declaring the surefire plugin later in pom.xml, as I saw in other questions, to run the tests later too, the build did not download the driver before.

What am I doing wrong? Any help would be appreciated.

Answer 1

You need to be aware of the Maven lifecycle (see Introduction to the Build Lifecycle), which dictates the order in which maven processes your build.

In your case, you have specified <phase>package</phase> for your maven-antrun-plugin execution, which comes after test.

I would use something like <phase>process-test-resources</phase> for your use case.
