I made another clean project with command prompt and ran into the same issue. Using fresh installations of jdk1.8.0_111 and apache-maven-3.3.9. M2_HOME, JAVA_HOME are set properly. gwt-2.8.0 folder was added to PATH. Btw, here's the only related topic I found so far https://groups.google.com/forum/#!topic/google-web-toolkit-contributors/fdWmFBtKvGA <https://groups.google.com/forum/#!searchin/Google-Web-Toolkit-Contributors/java.lang.NoClassDefFoundError$3A$20org$2Fapache$2Ftools$2Fant$2Ftypes$2FZipScanner|sort:relevance/google-web-toolkit-contributors/fdWmFBtKvGA/WQO1bdyqCgAJ>
