When i try to compile(running maven install) in the eclipse,i am getting an error of not compatibility.It seems that,for some reason,maven uses old jre/jdk and doesn't use the one specified in the Path env. variable.Even though when i run mvn -v,it outputs that maven uses the correct version(on my local machine)

How should i fix this?And can i do it without specifying each time in the POM.xml which version to use,but to tell maven to use the Path env. var. ? Here is what is specified in the eclipse:
This is the JAVA_HOME env. var.
This is the MAVEN_HOMEenv. var.
Here — the outputs of mvn -v and java -version
Here is the PATH env. var:
.
And here is my POM.xml

Even running mvn install from command line doesn't help.
