pmd-eclipse-plugin version: 4.40.0.v20221029-0812-r

The following line in Java code causing ERROR n.s.p.e.runtime.cmd.BaseVisitor - Runtime exception visiting and net.sourceforge.pmd.lang.java.ast.ParseException

${CLASS:emxContextUtil}.mqlNotice(context, returnMessage);

In my java code i had used ${ at many places due to this I am getting run time exception

pmd-eclipse.log:

@adangel how to resolve this "${" run time exception?

[adangel]

This ${CLASS:emxContextUtil} doesn't look like a valid identifier for a variable in Java.
It looks more like a placeholder, that is replaced before the java compiler sees your code...

Do you use any plugin in eclipse, that replaces these placeholder on the fly? Otherwise you should also see compile errors in eclipse...

PMD can only analyze files, that the java compiler can parse.

How does a complete java file in your case look like? Where is ${CLASS:emxContextUtil} defined?

[nagadheerajb]

Hello @adangel

I will add dependency jar files which replaces the placeholder on the fly, so there won't be any compilation errors.

The ${CLASS:emxContextUtil} is the java file (emxContextUtil_mxJPO.java) and it is calling the method mqlNotice and java file is placed on the same folder along with other source files
public static void mqlNotice(Context context, String notice) throws Exception
{
MqlUtil.mqlCommand(context, "notice $1", notice);
}

Reagards,
Naga Dheeraj

Sorry, I don't understand. What dependency jar exactly?
