Selenium 2和OperaDriver：java.net.BindException

我從https://github.com/operasoftware/operadriver/下載了OperaDriver，並試圖運行簡單的/ Example.java 但我總是得到一個異常「java.net.BindException：地址已經在使用」？我不明白這個BindException如何發生？我如何知道哪個端口已被佔用？它沒有打印出堆棧跟蹤？ OperaDriver默認運行在哪裏？Selenium 2和OperaDriver：java.net.BindException

以下是完整的堆棧跟蹤：

歌劇的webdriver使用Opera在Scope協議通信：默認情況下這個運行在端口7001

謝謝你的提示！是否有可能更改該默認端口？如果是，如何？ –

@Peter這並不容易，但您可以通過轉到opera：config並轉到Developer Tools/Proxy Port來更改默認端口。您還需要在這裏更改OperaDriver中的端口：'src/com/opera/core/systems/scope/internal/OperaIntervals.java：33：SERVER_PORT（7001）'。支持適當更改端口應該在幾個月內到來。 –
