Error
Sat Feb 06 15:12:10 CST 2016
Unable to acquire PluginConverter service during generation for: ~/develop/java/sts-bundle/sts/dropins/ER-diagram-editor-for-eclipse.

原因是eclipse版本过高,不支持旧的插件,

解决办法;

go to Help -> Install New Software..., choose "The Eclipse Project Updates - http://download.eclipse.org/eclipse/updates/4.5/" from the "Work with" list and then in the "Eclipse Tests, Examples, and Extras" category check "Eclipse 2.0 Style Plugin Support" and install it. After restarting Eclipse, install veloeclipse again and this time the installation will succeed.

上面的4.5是我的eclipse版本,改成你的eclipse版本即可.

安装完后重启即可.
