[Jasper Report syntax error on compiling]

• Jasper report - Netbeans latest plugin for ireport (plugin for 7.4)
• JDK - 1.8
• Netbeans 8.2

I am using java 8 streams inside the jrxml file. Stream function working fine outside the jrxml and when I compile the report It gives me below error :

Compilation exceptions: com.jaspersoft.ireport.designer.compiler.ErrorsCollector@3155ed77net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:1.

Here is my variable expression :

<variableExpression><![CDATA[$F{memberLoans}.stream().sorted(java.util.Comparator.comparing(p -> p.getId())).filter(p -> !p.isIsComplete()).filter(p -> p.isStatus()).filter(com.court.handler.FxUtilsHandler.distinctByKey(p -> p.getMemberLoanCode())).collect(java.util.stream.Collectors.toList())]]></variableExpression>[/code]

I already add my application jar and latest jdt-compiler jar to the classpath and changed the source to 1.8 as well but still It gives me the above mentioned error.

Any suggestion would be really helpful. Thank you.
