从pom.xml java获取变量

Question

I am using eclipse with maven for a mobile automation test on a mobile webpage.

I am defining the following in my pom.xml

<properties>
    <MY_VARIABLE>www.google.com/</MY_VARIABLE>
</properties>

but when i am calling this using

String testurl1 = System.getProperty("MY_VARIABLE");

it always seems to return null.

I also tried the following way of defining variable

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.16</version>
    <configuration>
        <systemPropertyVariables>
        <MY_VARIABLE>www.google.com</MY_VARIABLE>
        </systemPropertyVariables>
    </configuration>
</plugin>

but still am getting the value as null.

I could use some help Thanks.

Your configuration will not work in eclipse since there is no good m2e support for surefire. The maven surefire plugin forkes a new process and provides the systemPropertyVariables to it. Your configuration will work if you run the tests from the command-line, eg

mvn surefire:test

To make it run in both worlds (command-line and eclipse) I do it this way...

1. Create a src/test/resources/maven.properties

2. Edit the maven.properties file and put the properties you need in it, eg

    project.build.directory=${project.build.directory} MY_VARIABLE=${MY_VARIABLE} 

3. Enable resource filtering for test resources

    <build> <testResources> <testResource> <directory>src/test/resources</directory> <filtering>true</filtering> </testResource> </testResources> ... </build> 

4. Load the properties in your test and access them

     Properties mavenProps = new Properties(); InputStream in = TestClass.class.getResourceAsStream("/maven.properties"); mavenProps.load(in); String buildDir = mavenProps.getProperty("project.build.directory"); String myVar = mavenProps.getProperty("MY_VARIABLE");
