為了建置SDN測試平台，我安裝了Vmwarestations 14 pro來執行Mininet和OpenDayLight控制器。因此，為了安裝和運行 OpenDayLight，我遵循了教程。直到我嘗試sudo ./distribution-karaf-0.4.0-Beryllium/bin/karaf從 vmware 終端機執行此命令時才出現問題。
它向我顯示以下訊息：
karaf: JAVA_HOME not set; results may vary
./distribution-karaf-0.4.0-Beryllium/bin/karaf: 242: [:Illegal number:
OpenJDK 64-Bit Server VM warning: ignoring option Unsyncloadclass; support was removed in 11.0

Endorsed standards and standalone APIs in modular form will be supported via the concept of upgradeable modules.
Error: Could not create the java virtual machine.

如何解決這個問題？

對於 opendaylight，您需要 openjdk-8，但您已經安裝了 openjdk-11。這從 Ubuntu 運行 Opendaylight可能會幫助你
