今天使用 Drools 7.7.0.Final 時出現(xiàn)找不到 com.thoughtworks.xstream.XStream.setupDefaultSecurity的錯誤，

于是嘗試加入了 XStream的包：

  compile ("com.thoughtworks.xstream:xstream:1.4.9")

結(jié)果還是一樣的報錯，點擊查看源碼的時候真沒在 XStream的類里找到 setupDefaultSecurity。
這時候考慮到是不是版本的問題，去XStream的官網(wǎng)找到最新版是 1.4.10。

于是

  compile ("com.thoughtworks.xstream:xstream:1.4.10")

最終解決了這個錯誤。

Exception：

java.lang.NoSuchMethodError: com.thoughtworks.xstream.XStream.setupDefaultSecurity(Lcom/thoughtworks/xstream/XStream;)V
