Using robotframework python libraries in mvn projects

问题

I'm starting a new RobotFramework project, but I'm using the mvn plugin to manage the project. I want to add some python libraries (I have python installed on my computer), but when I try to run the project using the mvn run command, there are several errors related with the lack of python libraries installed.

If I run the project using the Pybot command, everything works fine. How can I use Python libraries when I'm using the maven plugin? Or can I add the Pybot command to the pom.xml?

回答1:

I assume that you already installed requests library, as alpert said, it's not a built in library.

And since you use maven, add the path_to_python_libraries to the robotframework plugin in the pom.xml file. In my case the path is /Library/Python/2.7/site-packages

In pom.xml, use extraPathDirectories tag in robotframework plugin to include the mentioned path. This is a sample of how the robotframework plugin would look like with the extraPathDirectories used to specify a the path_to_python_libraries:

<plugin>
    <groupId>org.robotframework</groupId>
    <artifactId>robotframework-maven-plugin</artifactId>
    <version>1.4.5</version>
    <executions>
        <execution>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <includes />
        <excludes />
        <criticalTags />
        <testCasesDirectory>${project.basedir}/path-to-suites
        </testCasesDirectory>
        <outputDirectory>${project.basedir}/target/path-to-output
        </outputDirectory>
        <extraPathDirectories>
            <extraPathDirectory>/Library/Python/2.7/site-packages
            </extraPathDirectory>
        </extraPathDirectories>
    </configuration>
</plugin>
