Deploying grails project in tomcat server

I'm getting the Valiate Jar file error when deploying the application in tomcat 7.0.57.Chaning the tomcat version to 8 is the only solution for this problem? This is my Error log:

org.apache.catalina.loader.WebappClassLoader validateJarFile INFO: validateJarFile(/home/webapps/myapp/WEB-INF/lib/tomcat-embed-core-8.0.32.jar) - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/servlet/Servlet.class org.apache.catalina.loader.WebappClassLoader validateJarFile INFO: validateJarFile(/home/webapps/myapp/WEB-INF/lib/tomcat-embed-el-8.0.32.jar) - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/el/Expression.class org.apache.catalina.deploy.WebXml setVersion WARNING: Unknown version string [3.1]. Default version will be used.

After Deploying the application in Tomcat server 8 I get the below error:

SEVERE: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[az84cimap02.am.freescale.net].StandardContext[/cienold] Caused by: java.lang.NullPointerException at org.apache.jasper.servlet.TldScanner$TldScannerCallback.scanWebInfClasses(TldScanner.java:401) SEVERE: Error deploying web application archive /home/cimwebadm/tomcat_instances/cien-grails/webapps/cienold.war java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component

Go to your build.gradle file and change

compile "org.springframework.boot:spring-boot-starter-tomcat"

to

provided "org.springframework.boot:spring-boot-starter-tomcat"

Then your war will deploy to Tomcat 7 as well.
