Hello,
I recently installed Myeclipse 10.1. I pulled in an existing project and had added a JDK5 “JRE” as this project was currently being built on Java5. A bit later I wanted to experiment building this project using Java6. I updated the build path and java compiler compliance etc. to Java 1.6. However, at that point I received the following error: “Java compiler level does not match the version of the installed Java project facet.”
I found a very helpful post from 2011 in this forum under the subject: “How to change the java project facet version?” (now locked). It described how to enable the Facet menu to appear under a project’s preference menu – which worked fine for me. The post indicated that the “facet” menu would be enabled by default in Myeclipse 9.1 – however, it looks like it is still disabled by default in 10.1. I believe it would be useful to have this enabled by default – as I assume this type of error will appear for anyone converting projects from 1.5 to 1.6 etc.
Just my two cents… Thanks –
