I use the SpringSource Tool Suite with the FlashBuilder 4.5 plugin. I recently tried to install the Code Coverage Plug-in using the instructions on the web page http://www.adobe.com/devnet/flash-builder/articles/ascode-coverage.html Unfortunately, I have not found a way to get this to work. I have placed the com.adobe.flash.codecoverage_4.0.2.jar in the sts-2.6.1.SR1/plugins directory as specificed. After restarting my IDE I cannot find the Coverage perspective as identified. I have copied the .jar file to my Adobe/FlashBuilder4.5/plugins directory and coverage shows up when running FB; however, although I installed the plugin by using the tool in the FB 4.5 utilities directory and it works perfectly in STS, I can't get the coverage plugin to show up in STS. Any ideas?
