How to get the absolute folder location of a Jmeter .jmx project file from within itself?

If you're looking for the way to locate current script when you run JMeter in GUI mode you can try the following Beanshell expression:

${__BeanShell(import org.apache.jmeter.gui.GuiPackage;GuiPackage.getInstance().getTestPlanFile();)}

If you brake this down into 5 lines there will be:

import org.apache.jmeter.gui.GuiPackage;
import org.apache.commons.io.FilenameUtils;
String testPlanFile = GuiPackage.getInstance().getTestPlanFile();
String testPlanFileDir = FilenameUtils.getFullPathNoEndSeparator(testPlanFile);
vars.put("testPlanFileDir", testPlanFileDir);
log.info("testPlanFileDir:" + testPlanFileDir);

Your current .jmx file fill be stored as scriptFile JMeter Variable.

The solution was (thanks to Ardesco) to do the following:

Use the following variables, set in the Test Plan global variables:

projectHome = ${__BeanShell(import org.apache.jmeter.services.FileServer; FileServer.getFileServer().getBaseDir();)}
jmeterHome = ${__BeanShell(System.getProperty("user.dir");)}
scriptHome = ${projectHome}/scripts
