tomcat無法在jpda啟動模式下啟動
這是我的catalina.sh

ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options. Error occurred during initialization of VM agent library failed to init: jdwp而且我無法在 Eclipse 中進行遠端調試
但是如果我啟動正常的tomcat正在啟動
您應該在 JAVA_OPTS 環境變數中設置開關，或者將參數傳遞給，但不能同時傳遞。如果你兩者都做，它會嘗試載入代理兩次並給你一個錯誤。
-Xdebug -Xrunjdwp...``jpda``catalina.sh編輯：我個人更喜歡使用 JAVA_OPTS 開關，因為它們提供了更多控制權（例如設置埠號）。完成此操作並重新啟動 Tomcat 後，您應該能夠從 Eclipse 與調試器連接。
要從 Eclipse 連接，您需要創建類型為“Remote Java Application”的調試配置： 從“執行”菜單中，選擇“調試配置…”。在左側窗格中，選擇“遠端 Java 應用程序”並點擊“新建”按鈕。在右側窗格中，選擇項目，然後在主機欄位中輸入 Tomcat 伺服器的 IP 地址。您可以保留其他欄位的預設值。然後點擊底部的 Debug，Eclipse 調試器應該連接到 Tomcat。
