TestNG in Eclipse, Reference to undefined variable env.DOMAIN_PATH - eclipse

Question

I just got a error when I try to run a unit test in Eclipse with TestNG, the error message is: Reference to undefined variable env.DOMAIN_PATH
but this problem does not exist when I run it in Intellj or with maven.
any one experience this problem?
I use Eclipse Mars.2 Release (4.5.2), and updated TestNG plugin version 6.9.12.201607091356
thanks.

Answer 1

When I was trying to run TestNG, I got the same error. I changed the preferences in Eclipse for TestNG -> Maven so that systemPropertyVariables and environmentVariables are unchecked, and I was able to run the test cases successfully.

Answer 2

I faced the same issue. and for me, it worked by unchecking all the options from
Preferences->TestNG-> Maven.

Answer 3

you need to enable the 'environmentVariables' option at either Eclipse workspace level preferences or project level properties, for example for workspace level: navigate to Eclipse preference -> TestNG -> Maven -> enable option 'environmentVariables'. By default it's disabled.
see more details in the official guide

Answer 4

Just uncheck System Property Variables from Preferences->TestNG->Maven.

Answer 5

It works just by disabling systemPropertyVariables under Window--> Preferences --> TestNG --> Maven

Answer 6

In case you are working with maven project, setting your custom property to some default value could resolve this issue. below is a sample.
<properties>
<environment>local</environment>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<systemPropertyVariables>
<environment>${environment}</environment>
</systemPropertyVariables>
</configuration>
</plugin>
</plugins>
</build>
you can make use of "environment" property in project using below call.
System.getProperty("environment");

I unchecked everything and left just the argline checked, and this worked for me
