如何更改 libgdx 项目的 Java 版本?
How to change Java version of libgdx project?
我正在使用 libgdx java 库创建简单的游戏,但不知道如何更改项目的 java 版本。
问题:它使用 1.7,我正在尝试将其更改为 1.8
我试过的东西(参考):
在项目结构 > 项目中将 sdk 版本更改为 1.8
模块部分每个模块的更改版本
试图用 1.8 java
将 build.gradle 文件修改为 运行
构建脚本{
repositories {
mavenLocal()
mavenCentral()
gradlePluginPortal()
maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
google()
}
dependencies {
classpath 'org.wisepersist:gwt-gradle-plugin:1.1.16'
classpath 'org.gretty:gretty:3.0.7'
}
}
allprojects {
apply plugin: "eclipse"
version = '1.0'
ext {
appName = "Mario"
gdxVersion = '1.11.0'
roboVMVersion = '2.3.16'
box2DLightsVersion = '1.5'
ashleyVersion = '1.7.4'
aiVersion = '1.8.2'
gdxControllersVersion = '2.2.1'

您将 sourceCompatibility
更改为 1.8 的方法是正确的,但是您在错误的文件中进行了更改。在一个 libgdx 项目中有 几个 build.gradle 文件。
在您的根目录(您在问题中找到 build.gradle 文件的位置)中,有一个目录 core
。在这个项目中还有另一个 build.gradle,其中包括 sourceCompatibility
.
该文件应如下所示:
sourceCompatibility = 1.7 // change to 1.8 here to use java-8 features
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'
sourceSets.main.java.srcDirs = [ "src/" ]
eclipse.project.name = appName + "-core"
