in my libgdx gradle app I have a class of GroundHandler:
package com.mygdx.physics
import com.badlogic.gdx.ApplicationAdapter
import com.badlogic.gdx.Gdx
import com.badlogic.gdx.math.Vector2
import com.badlogic.gdx.physics.box2d.Fixture
import com.badlogic.gdx.physics.box2d.Body
import com.badlogic.gdx.physics.box2d.BodyDef
import com.badlogic.gdx.graphics.OrthographicCamera
import com.badlogic.gdx.physics.box2d.PolygonShape
import com.badlogic.gdx.physics.box2d.World
class GroundHandler(val world: World, val camera: OrthographicCamera) {
private var groundBodyDef: BodyDef = BodyDef()
private var groundBox: PolygonShape = PolygonShape()
private var groundBody: Body? = null
fun createGround() {
groundBodyDef.position.set(Vector2(0f, 10f))
groundBody = world.createBody(groundBodyDef)
groundBox.setAsBox(camera.viewportWidth, 10.0f)
groundBody?.createFixture(groundBox, 0.0f)
groundBox.dispose()
}
}
which is used in a different class. at first it compiles well, but when app window starts i get
Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics

all i did to this was changing 'java' to 'kotlin' two times and added kotlin dependency to buildscript {}
Just add jar{} section indo desktop.gradle like this:
apply plugin: "kotlin"
sourceCompatibility = 1.6
sourceSets.main.java.srcDirs = [ "src/" ]
project.ext.mainClassName = "com.your.class.name"
project.ext.assetsDir = new File("../android/assets");
jar {
manifest {}
from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}

I was attempting to run a libgdx project that was cloned from a git repository. However, everytime I run the desktop launcher, I get the following error:

Also do note that I am running the program on a MacOS. Could this be an OS-specific issue and are there any solutions to this problem?
I'm trying a libgdx project depending on a lib published in local repo with maven-publish:
// to publish locally:
// ~/gdx-gltf$ ./gradlew gltf:publishToMavenLocal
apply plugin: 'maven-publish'
publishing {
publications {
mavenJava(MavenPublication) {
groupId = 'io.github.odys-z'
artifactId = 'gdx-gltf'
version = '0.1.0-SNAPSHOT'
from components.java
}
}
}
When I running the depending desktop with gradlew CLI, it's working:
./gradlew desktop:run
But in eclipse and right click the BasicTweenTest class (gradle project.ext.mainClassName) and run as java application, eclipse reported errors:
com.badlogic.gdx.utils.GdxRuntimeException: java.lang.Error: Unresolved compilation problems:
sceneAsset cannot be resolved to a variable
GLTFLoader cannot be resolved to a type
SceneModel cannot be resolved to a type
scenes cannot be resolved or is not a field
animationLoader cannot be resolved to a variable
The missing type is in the local repo dependency, gdx-gltf-0.1.0-SNAPSHOT. No matter what I cleaned projects or refreshed gradle, the error persisting appear.

The other two tests commented out above can run both in CLI and eclipse, which don't depend on the local published package. Any idea?

I faced the same problem. Turns out that LibGDX works with JDK 7 and any version compiled above won't work.
You need to enforce java to compile at version 1.7 before publishing locally
apply plugin: 'java'
sourceCompatibility = 1.7
targetCompatibility = 1.7
As the title says. I'm using IntelliJ IDEA 2017.1.4
My gradle file is following:
group 'org.ks'
version '1.0-SNAPSHOT'
buildscript {
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "org.springframework.boot:spring-boot-gradle-plugin:1.4.7.RELEASE"
}
}
apply plugin: "org.springframework.boot"
task wrapper(type: Wrapper) {
gradleVersion = '2.4'
}
apply plugin: 'java'
apply plugin: "io.spring.dependency-management"
sourceCompatibility = 1.8
targetCompatibility = 1.8
But the attempt to use #Autowired annotation causes compilation error
package app;
import org.springframework.beans.factory.annotation.Autowired;
public class AutowiredCls {
#Autowired
private int app_name;
}
Compiler marks import and #Autowired as errors (red underline)
application.yml:
app.name = autowired_sample
What do I do wrong?
Please add below dependencies, you can refer to this for more details
dependencies {
// tag::jetty[]
compile("org.springframework.boot:spring-boot-starter-web") {
exclude module: "spring-boot-starter-tomcat"
}
}
It doesn't look like your project has any dependencies at all. (I can see that your buildscript has dependencies... but these will not apply to the project sources thamselves.)
Here is a build.gradle file from a project I once generated using https://start.spring.io:
buildscript {
ext {
springBootVersion = '1.3.5.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse-wtp'
apply plugin: 'spring-boot'
apply plugin: 'war'
war {
baseName = 'soffit-samples'
version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
}
configurations {
providedRuntime
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-cache')
compile('org.springframework.boot:spring-boot-starter-web')
providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
eclipse {
classpath {
containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
}
}
The project itself (my sources) contains 2 dependencies defined for the compile scope:
org.springframework.boot:spring-boot-starter-cache
org.springframework.boot:spring-boot-starter-web
Both of these are Spring dependencies. I imagine that one (or both) of these give my sources access to the #Autowired annotation... either directly or transitively (probably transitively).
FYI - I 've found the solution. It's best to visit start.spring.io to generate gradle.

I am trying to configure scala in my libgdx project with the gradle build tool, as written in this article https://github.com/libgdx/libgdx/wiki/Using-libgdx-with-Scala.
I edited allproject and the core gradle files as written in the article. After that i changed my MyGdxGame class from java class to scala class. and after i tried to start the desktop laucher i got the error - Gradle : error : cannot find symbol class MyGdxGame.
How can i solve this issue?

I would recommend you set a variable for the google services and make them all the same version.
For example, your BaseGameUtils uses 8.4.0 consistently, but your project is using various other versions (9.6.1 and 9.4.0)
ext {
appName = "RocketHedgehog"
gms_library_version = "8.4.0" // For consistency with library
Then, update these lines to use that variable.
compile "com.google.android.gms:play-services-ads:${gms_library_version}"
compile "com.google.android.gms:play-services-games:${gms_library_version}"
