的Grails無法加載oracle.jdbc.driver.OracleDriver和--refresh依賴性不起作用

我得到ClassNotFoundException的在我的項目/ lib中有oracle驅動程序.jar）。的Grails無法加載oracle.jdbc.driver.OracleDriver和--refresh依賴性不起作用

我已經看到了類似的問題here和其他地方，答案似乎總是跑--refresh-depdencies

然而，我發現，這樣做只能用於--refresh依賴性之後只有一個時間運行。隨後的任何時間我都會運行應用程序，我再次獲得ClassNotFoundException：oracle.jdbc.OracleDriver，直到我再次運行--refresh-dependencies。通過運行--refresh-dependencies每次我即將運行應用程序，我仍然可以運行，但它很煩人。

我正在運行grails 2.3.0。

Grails的輸出而不必做--refresh依賴性之前立即運行的應用程序：

，做--refresh依賴性之後：

嘗試升級到2.3.4或至少是2.3.0以外的版本 - 兩個版本之間修復了很多錯誤 –

我升級到2.3.4，並且仍然遇到同樣的問題。 – shazbot

這看起來像一個問題在2.3中默認使用了新的Aether依賴管理器。它的速度比一般的速度快很多，但常常不支持的少數Ivy功能。

我能夠從以太改變常春藤在BuildConfig.groovy得到這個工作：

grails.project.dependency.resolver = "ivy"

不幸的是，這導致我沒有任何改變。 – shazbot

嘗試運行'grails compile --refresh-dependencies' –

我已經這樣做了，因爲這樣做是複製問題的一部分。和以前一樣，當運行grails編譯--refresh-dependencies時，當run-app立即運行時，不會出現問題，但是隨後運行run-app的任何時間都會出現問題，除非grails編譯--refresh-dependencies再次運行。 – shazbot

我不認爲這是一個「答案」我自己的問題，但我在這裏張貼作爲一個可能的解決方案，以防其他人遇到此問題。

我能夠通過通過BuildConfig.groovy而不是使用/ lib文件夾拉動我的oracle驅動程序來解決這個問題。

我不認爲這是一個解決方案的原因是，爲了做到這一點，您需要一個存放oracle驅動程序工件的存儲庫，它不在任何公共存儲庫中，也不允許由於「吝嗇」在甲骨文的一部分。

我的公司有一個私人存儲庫，我可以使用該存儲庫，並由我們的CI服務器共享，並且此解決方案僅適用於那些有權訪問某種私人存儲庫的人。我把我的BuildConfig.groovy幾乎是你所期望的：

runtime "com.oracle:ojdbc6:11.2.0.1.0"

那些在它仍然需要一個解決無法使用此解決方案由於沒有提供與Oracle驅動程序jar的倉庫使用/ lib時出現的問題。

我有類似的問題，一次它會運行應用程序很好，但只要我重新啓動它會拋出「池連接」異常。

在BuildConfig.groovy中添加以下行修復了我的問題。不知道爲什麼它缺少開始。

grails.project.dependency.resolver = "maven" // or ivy

從此改變行我BuildConfig：

runtime "com.oracle:ojdbc6:11.2.0.1.0"

這（離開了COM）：

runtime "oracle:ojdbc6:11.2.0.1.0"

爲我工作。
