我已经使用以下版本为MAC构建了jcef MAC 10.13.4
Xcode 9.3
java 1.8.0_171和1.8.0_191都尝试过
根据说明https://bitbucket.org/chromiumembedded/java-cef/wiki/BranchesAndBuilding构建的JCEF
用于Java开发人员的Luna Service Luna Service Release 1（4.4.1）
我创建了一个eclipse项目并导入了所有jar，在项目中复制了Release文件夹，然后我尝试按照MainFrame.java示例运行

address_.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
browser_.loadURL(address_.getText());
}
});
getContentPane().add(address_, BorderLayout.NORTH);
getContentPane().add(browerUI_, BorderLayout.CENTER);
pack();
setSize(800, 600);
setVisible(true);
addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
CefApp.getInstance().dispose();
dispose();
}
});
}
public static void main(String[] args) {
// Perform startup initialization on platforms that require it.
try {
String libpath = "<path to project>/jcefdemo/Release";
System.setProperty("java.library.path",libpath);
final Field sysPathsField = ClassLoader.class.getDeclaredField("sys_paths");
sysPathsField.setAccessible(true);
sysPathsField.set(null, null);
if (!CefApp.startup()) {
System.out.println("Startup initialization failed!");
return;
}
boolean useOsr = false;
new MainFrame("http://www.google.com", true, true);
System.out.println("Startup ");
} catch (Exception e) {
e.printStackTrace();
}
}
}
但出现错误
