11.2.0
提示 cannot find a j2se sdk
并不是找不到正确的java?将启动developer的快捷方式修改下
需要安装gitbash之类的解释器
Start Menu > Oracle - OraDb11g_home1 > Application Development > SQL Developper -> Properties
CHANGE "Target" By : C:\app\ORACLE_HOME\product\11.2.0\dbhome_1\sqldeveloper\sqldeveloper.sh
CHANGE "Start In" By : C:\app\ORACLE_HOME\product\11.2.0\dbhome_1\sqldeveloper
