idea下載多個外掛專案啟動不了解決方案
阿新 • • 發佈：2019-02-18
今天下載mybatis plugin外掛的時候
有好多個版本的plugin，然後呢，看第二個比較熱門，就下載了第二個，然後重啟idea發現這個外掛貌似得花錢，那算了吧，咱用第一個免費的吧，就又下載了第一個，然後重啟idea。然後。。。就炸了。
瞬間感覺心慌慌的，最後還是藉助百度解決了。。
首先看上面那個報錯資訊，一看就很像jar包衝突的報錯資訊，先放著，我們再看看idea的日誌：C:\Users\{username}\.IntelliJIdea2016.1\system\log\idea.log。在這個路徑下，開啟idea.log。找到剛剛的報錯資訊：

最後一段看似和idea啟動的時候那個報錯差不多。應該是jar包衝突了，但是jar包叫什麼名字，在什麼地方呢，這是個問題，windows的檔案搜尋很難找。
於是，下載了一個Everything （該工具可以實現秒查電腦上任意位置的任意檔案，堪稱本地檔案搜尋神器，下載地址:http://www.voidtools.com/）。隨意的搜了下mybatis，然後按時間排個序，看似找到了。
應該是這兩個jar衝突了，刪掉那個收費的試試。然後重啟idea。完美解決~
