From what I see in the current com.google.gdt.eclipse.maven.e37_3.4.2.v201310081834-rel-r43.jar, src/main/webapp is hardcoded when calling WebAppProjectProperties.setWarSrcDir.

GWT WAR directory is not set properly in Eclipse Google (GWT) plug-in --------------------------------------------------------------------- Key: JBIDE-16334 URL: https://issues.jboss.org/browse/JBIDE-16334 Project: Tools (JBoss Tools) Issue Type: Bug Components: maven Affects Versions: 4.1.0.Final Environment: Eclipse Kepler m2e 1.2 m2e-wtp 1.0.1 Google Plugin for Eclipse 3.4.2 JBoss Maven GWT Configurator 1.5.4 Reporter: Slawa Giterman Assignee: Denis Golovin Hello, I use Eclipse Kepler, m2e 1.2, m2e-wtp 1.0.1, Google Plugin for Eclipse 3.4.2 and JBoss Maven GWT Configurator 1.5.4. My project uses not default warSourceDirectory in Maven pom.xml (<warSourceDirectory>$\{basedir\}/WebContent</warSourceDirectory>). The problem is that after each Maven -> Update Project action, GWT WAR directory in Eclipse (Project -> context menu -> Google -> Web Toolkit Settings -> Web Application -> WAR directory) is set to default Maven value "src/main/webapp" and not to the value of warSourceDirectory from pom.xml. It seems that WAR Directory value is read from file <ECLIPSE_PROJECT>/.settings/com.google.gdt.eclipse.core.prefs, property *warSrcDir*. This file has also another property, *lastWarOutDir* which tells Google GWT Plugin where to compile the GWT code (this issue was solved in JBIDE-11224) Current content of com.google.gdt.eclipse.core.prefs after Maven -> Update Project: {code}lastWarOutDir=/applicationserver/WebContent warSrcDir=src/main/webapp{code} So, the question is, is it possible to set value of warSrcDir to the same value as lastWarOutDir so that Eclipse does not show error "WAR source directory /applicationserver/src/main/webapp is missing" after each update?
