I'm writing something (a map generator) using the LibGDX library, which has the ability to build a HTML5 deployable using GWT.
However, when I run the Gradle build I receive this error:
:html:compileGwt
Compiling module technology.rocketjump.undermount.mapgen.GdxDefinition
Validating units:
[ERROR] Errors in 'file:/D:/workspace/undermount-mapgen/core/src/main/java/technology/rocketjump/undermount/mapgen/generators/RiverGenerator.java'
[ERROR] Line 61: RiverPathfindingCalculator cannot be resolved to a type
[ERROR] Line 89: The left-hand side of an assignment must be a variable
The error seems to be indicating the following lines in RiverGenerator.java
private boolean runRiver(GridPoint2 startPoint, GridPoint2 endPoint, GameMap map) {
RiverPathfindingCalculator pathfinder = new RiverPathfindingCalculator(startPoint, endPoint, map);
List<GridPoint2> path = pathfinder.findPath();
However RiverPathfindingCalculator
is just another Java class in the same project. It seems to be imported correctly in the file too, here's the imports of RiverGenerator
package technology.rocketjump.undermount.mapgen.generators;
import com.badlogic.gdx.math.GridPoint2;
import technology.rocketjump.undermount.mapgen.calculators.RiverPathfindingCalculator;
import technology.rocketjump.undermount.mapgen.model.TileType;
import technology.rocketjump.undermount.mapgen.model.output.*;
import java.util.*;
You can view the relevant code on Github. Any ideas on what I'm doing wrong or how to fix this?
GWT < Version 2.8 doesn't support java8 syntax, so no lambda expressions.
Rewrite that lambda to a "normal" Comparator (most IDEs have a refactoring to do it automatically) and GWT should be happy.
