Some suggestions (that have been already mentioned in this thread a while
ago):
1, use gwt-maven-plugin 2.5.1 instead of 2.4.0
in root pom.xml change
<gwt-maven-plugin.workingRefresh.version>2.4.0</gwt-maven-plugin.workingRefresh.version>
to
<gwt-maven-plugin.workingRefresh.version>${gwt.version}</gwt-maven-plugin.workingRefresh.version>
2, disable GWT persistent unit cache
in frontend/webadmin/modules/pom.xml find
<artifactId>gwt-maven-plugin</artifactId>
add <persistentunitcache>false</persistentunitcache> to
<configuration>
-or-
make gwt-debug [usual options]
DEV_EXTRA_BUILD_FLAGS="-Dgwt.persistentunitcache=false"
3, try out GWT Super Dev Mode
Vojtech
Vojtech, you're not experiencing this slowness?
