Description of problem: As mentioned in bz 1192479 comment 1, current ER5 build wasn't compiled with full profile that includes GWT permutations for all supported browsers. Version-Release number of selected component (if applicable): 6.1.0.ER5 Actual results: Only 2 .cache.html files in business-central.war/org.kie.workbench.drools.KIEDroolsWebapp/. Consequent issues like bz 1192479 and impossibility to log into business central with IE. Expected results: Usually there is 28 .cache.html files in business-central.war/org.kie.workbench.drools.KIEDroolsWebapp/. Additional info:
The kie-wb-distribution was indeed intentionally built without -full profile by me because after disucssion with developers, there is an issue blocked the product build which is "eap modules" needs higher maven tool chain. However eap modules are not actually needed for product build any more. So I ignored the full profile for walkaround the build issue. Now it obviously seems to be a mistake. However for ER6, I noticed that the "eap-modules" generation are still present in kie-wb-distributios, so this issue will still block the product build.
The solution is to recover the full profile for kie-wb-distribution but comment out the "kie-eap-integration" modules in pom.xml.
Verified with both BRMS and BPM Suite 6.1.0.ER6 that all distributions contain 28 .cache.html files.
