簽名過程中的SocketTimeoutException

Question

我們在自動化Maven構建過程中遇到了一些麻煩。這個構建會不時被install4j的簽名過程破壞。有時候它會很好運作，有時我們會得到以下例外：

這是穩定我們連續構建的問題。 SocketTimeoutException使我得出了與verisign服務器缺少連接的結論。但是對於更新程序，在簽署執行期間已經有一個連接。現在我不確定這是否可能是我們的構建環境或install4j本身的簽名過程的問題。什麼值被設置爲連接超時的默認值？是否可以重寫此值？

對於簽署，我們使用pfx -file和install4j與版本5.1.12。

Answer 1

默認情況下，讀取超時設置爲10000毫秒。您可以通過將

-Dinstall4j.readTimeout=20000 

添加到install4j安裝中的文件bin/install4j.vmoptions來增加它。

僅供參考，連接超時類似的虛擬機參數install4j.connectTimeout也有默認值10000毫秒。

更新（二零一四年十一月二十零日）：

由於install4j 6.0，失敗計數器簽名與3秒的暫停重試10次。最大重試次數可以通過VM參數增加

-Dinstall4j.counterSignRetry=20
