应用错误收集

我一直试图让GitLab CI在没有运气的情况下构建我的LWJGL项目，经过大约一个小时的修补我把它作为我的.gitlab-ci.yml：

image: java:8-jdk
buildtest:
 script:
 - mkdir bin
 - javac -cp dependencies/lwjgl/lwjgl.jar -d bin/ src/*.java
 - cd bin
 - java HelloWorld

然而，在最终正确编译之后，当运行代码时，它会得到以下日志：

$ mkdir bin
$ javac -cp dependencies/lwjgl/lwjgl.jar -d bin/ src/*.java
$ cd bin
$ java HelloWorld
Error: A JNI error has occurred, please check your installation and try again

ERROR: Build failed: exit code 1

在我看来它找不到org.lwjgl.glfw.GLFWKeyCallback，但是在本地编译时它可以正常工作。所以我无法弄清问题是什么，有什么想法吗？

编辑：

在搞砸了这个之后，我最终在我的机器上尝试了这个，以下工作在命令提示符下，但不是在shell脚本中，并且因为GitLab CI使用linux它也不能在那里工作。这是我编写的shell脚本，可以快速测试以及新错误：

mkdir bin
javac -cp dependencies/lwjgl/lwjgl.jar -d bin/ src/*.java
cd bin
java -cp ../dependencies/lwjgl/lwjgl.jar; -Dorg.lwjgl.librarypath=../dependencies/lwjgl/native/ HelloWorld

错误（我知道它对java.exe的用法，但它会打印出那个和最后的错误）：

bash: -Dorg.lwjgl.librarypath=../dependencies/lwjgl/native/: No such file or directory

我知道这个目录是存在的，因为我可以通过命令提示符以下列方式使它工作：

javac -cp dependencies/lwjgl/lwjgl.jar -d bin/ src/*.java
cd bin
java -cp ../dependencies/lwjgl/lwjgl.jar; -Dorg.lwjgl.librarypath=../dependencies/lwjgl/native/ HelloWorld

从命令提示符版本输出：

E:\test\bin>java -cp ../dependencies/lwjgl/lwjgl.jar; -Dorg.lwjgl.librarypath=../dependencies/lwjgl/native/ HelloWorld
Hello LWJGL 3.0.0b SNAPSHOT!

E:\test\bin>

您必须将库路径设置为包含本机文件的文件夹。

java -Dorg.lwjgl.librarypath=path/to/natives HelloWorld

您可以在LWJGL zip文件的.so文件夹中找到文件（结尾为.dylib，.dll和native）。

LWJGL使用GitLab CI构建
