IntelliJ IDEA - CodenameOne - AndroidStudio 安装/JDK 更改后找不到 CEF 路径？

【问题标题】：IntelliJ IDEA - CodenameOne - CEF path not found after AndroidStudio installation/JDK change?IntelliJ IDEA - CodenameOne - AndroidStudio 安装/JDK 更改后找不到 CEF 路径？
【发布时间】：2022-05-05 16:45:34
【问题描述】：

我在 Windows10 系统上遇到了这个问题。

我将 JDK 更改为 OpenJDK 1.8 以便能够发送 Android 版本。

虽然我暂时没有测试 CEF 浏览器部分，但在设备上该应用程序正在运行。

在模拟器上应用程序被执行，但在出现异常后被阻止（显示一个对话框）。

此外，如果我恢复到 Oracle JDK11，问题仍然存在。

该应用程序正常运行。我还在我的系统上安装了 AndroidStudio，可能它弄乱了 PATH。

我现在该如何解决这个问题？

（见下面的日志）

谢谢

Process finished with exit code 0

我重置了 IDE，现在我认为问题是：

Caused by: java.lang.UnsatisfiedLinkError: no jcef in java.library.path: [C:\Program Files\Java\jdk-11.0.2\bin, C:\WINDOWS\Sun\Java\bin, C:\WINDOWS\system32, C:\WINDOWS, C:\Program Files\Common Files\Oracle\Java\javapath, C:\Program Files (x86)\Intel\iCLS Client\, C:\Program Files\Intel\iCLS Client\, C:\WINDOWS\system32, C:\WINDOWS, C:\WINDOWS\System32\Wbem, C:\WINDOWS\System32\WindowsPowerShell\v1.0\, C:\WINDOWS\System32\OpenSSH\, C:\Program Files\Intel\Intel(R) Management Engine Components\DAL, C:\Program Files\Intel\Intel(R) Management Engine Components\IPT, C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL, C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT, C:\Program Files\dotnet\, C:\Program Files\Microsoft SQL Server\130\Tools\Binn\, C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\170\Tools\Binn\, C:\Users\user\AppData\Local\Microsoft\WindowsApps, ., C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2020.2.4\bin, ., C:\Users\user\AppData\Local\Programs\Microsoft VS Code\bin, C:\Users\user\.dotnet\tools, C:\Users\user\AppData\Local\Box\Box Edit\, .]

【问题讨论】：

  • JCEF 在与 IntelliJ IDEA 捆绑的 JetBrains Runtime 中可用，但在您使用的 JDK 1.8 中不可用。如果您的应用程序使用 JCEF，您需要使用与 IDE 本身运行时相同的运行时运行它（在 IDE 主目录的 jbr 子目录下）。
  • @CrazyCoder 我的项目似乎搞砸了。即使我更改了 JDK 路径，它们也会被覆盖。请你告诉我我必须设置的每个事件以及设置什么？
  • 项目结构 |项目 |开发工具包。运行配置 | JRE。
  • @CrazyCoder 请检查编辑后的帖子，我附加了一些信息。我认为问题在于环境变量中的路径。谢谢
  • JDK 没有开箱即用的 JCEF，只有 JetBrains Runtime 有。

【解决方案1】：

我猜java.library.path 已更改或 JCEF 二进制文件位于其他位置。

所以，首先您需要找出JCEF 二进制分发版 在哪里。通常此文件夹包含文件：

  • libcef.dll
  • libEGL.dll，
  • libGLESv2.dll
  • libcef.dll
  • libjcef.dll
  • jcef_helper.exe

如果您使用 unix 基础操作系统，则为 *.so 扩展名。

如果您没有 JCEF 的二进制分发版，您可以使用 link 从源代码构建它。我想警告你，这不是一帆风顺的旅程。在最后一步（打包）中，您将获得 binary_distrib 目录

其次，您的系统已经配置了查找 jcef 二进制文件的路径。您可以在异常详细信息中看到它：

java.library.path: [C:\Program Files\Java\jdk-11.0.2\bin, C:\WINDOWS\Sun\Java\bin , ...

或者您可以通过向 IDEA 添加 VM 选项并再次运行应用程序来验证它：

Edit Configurations -> Modify options -> Tick Add VM options -> In appeared field put -XshowSettings:properties

第三，您需要将 JCEF 二进制文件 放入其中一个java.library.path

希望这个建议对你有所帮助
