Considering question https://stackoverflow.com/a/51980599/7203487. Only one method among methods in class contains System.getenv which needs to be mocked. Problem is I require to take jacoco code coverage which I get as 0% due to use of powemock. Is there a way possible to mock system and attain code coverage with or without powermock?

Have a look into the System Rules for JUnit 4, especially the EnvironmentVariables.
public class EnvironmentVariablesTest {
@Rule
public final EnvironmentVariables environmentVariables = new EnvironmentVariables();
@Test
public void setEnvironmentVariable() {
environmentVariables.set("name", "value");
assertEquals("value", System.getenv("name"));
}
}
Adding to @Roland Weisleder.
EnvironmnetVariables is not part of junit . you need to add below dependency
https://stefanbirkner.github.io/system-rules/download.html
<dependency>
<groupId>com.github.stefanbirkner</groupId>
<artifactId>system-rules</artifactId>
<version>1.19.0</version>
<scope>test</scope>
</dependency>
