pom.xml中的LWJGL项目错误：缺少工件org.lwjgl：lwjgl-platform：jar：natives-windows：$ {lwjgl.version}

Question

So I'm trying to teach myself LWJGl for fun, so I make the project file, put the things into the pom.xml file, and then I get this error:

Missing artifact org.lwjgl:lwjgl-platform:jar:natives-windows:${lwjgl.version}

This is my pom.xml file:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

Any help would be appreciated, thanks :)

You should define a property for ${lwjgl.version} . As you can see at Maven Central , the only version of this artifact is 3.0.0 and you must explicitly define it. Please replace your <properties> tag with the following:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <lwjgl.version>3.0.0</lwjgl.version>
</properties>

Also, you might want to get use of the offical LWJGL page describing setting up Maven project, as I am not sure if your pom.xml includes all necessary dependencies.
