When Spoon 7.0/7.1 is launched the connect button on the right side of the screen does not appear. The issue is intermittent, and when it happens you have to close spoon and clear out the karaf cache data-integration/system/karaf/caches/spoon/data* and the button will reappear. 引用自 【翟心仁厚 2018/06/14 17:57】回答 https://www.oschina.net/question/1041591_2277281
