build.gradle

// Builds a Ghidra Extension for a given Ghidra installation.
//
// An absolute path to the Ghidra installation directory must be supplied either by setting the 
// GHIDRA_INSTALL_DIR environment variable or Gradle project property:
//
//     > export GHIDRA_INSTALL_DIR=<Absolute path to Ghidra> 
//     > gradle
//
//         or
//
//     > gradle -PGHIDRA_INSTALL_DIR=<Absolute path to Ghidra>
//
// Gradle should be invoked from the directory of the project to build.  Please see the
// application.gradle.version property in <GHIDRA_INSTALL_DIR>/Ghidra/application.properties
// for the correction version of Gradle to use for the Ghidra installation you specify.
