Question

我有一个项目，我使用maven和intellij。我使用TestFX，Mocito和PowerMock编写我的测试函数，但是当我逐个运行测试时，所有测试都会通过。但是当我开始运行所有测试时，它会给出这个异常。我搜索并添加System.loadLibrary（“glass”）它不起作用。我尝试了一些解决方案，但我无法解决。谁知道问题是什么？

虽然我做了linkte并尝试了其他解决方案，但我无法解决glass.dll not found错误。我正在寻找一个持久耐用的解决方案。

我的项目中遇到了同样的问题。我使用的是Java（在eclipse中）和Jboss服务器1.7。我对 jpeg.dll 也有这种错误。这个错误是因为错误地将库（.jar文件）放在我已经由Java提供的jboss / deployment /../ lib文件夹中。意思是，它是由java第一次加载，第二次由我的程序加载。所以这个错误。

解决方案是（这对我有用，你在最后检查） - Jboss里面有一个名为＆＃34; modules＆＃34;的文件夹，检查你的包裹并转到＆＃34; jdk /主＆＃34;夹。搜索 module.xml 。并添加依赖。我在我的代码中添加如下。

路径名=＆＃34; com / sun / image / codec / jpeg＆＃34;

然后重新启动服务器并重试。

只需查看/搜索您的dll所在的位置。就我而言，它存在于 com.sun.image.codec 包中。

这一切都在我身边。如果您需要进一步的帮助，请随时询问。
