I am trying to integrate my maven project with Tomcat server 8.5. Without integration, everything works fine. I replaced maven-compiler-plugin with tomcat7-maven-plugin in pom.xml and did other configurations. After that mvn install, mvn clean install and mvn tomcat7:deploy everything is failing with below exception.
TestServiceCSV.java:[345,48] strings in switch are not supported in -source 1.5
(use -source 7 or higher to enable strings in switch)
at org.apache.maven.lifecycle.internal.MojoExecutor.execute (MojoExecutor.java:213)
So clearly the compilation is being performed using java 1.5, whereas my jdk version is 1.8.0_144. Additional details below:
>mvn -version
Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T02:58:13-05:00)

>java -version

Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)
I have set the Installed JRE in Eclipse as the JDK. Also the build path for my project reflects same.
>echo $MAVEN_HOME

C:\Program Files\Java\jdk1.8.0_144

Why could the compilation is being performed on 1.5 instead of the actual version?
