Building -------- The el jars are not available on a public maven repository. You have to download the facelets 1.1.12 distribution (the el-api.jar and el-ri.jar has been renamed in the facelets 1.1.13 version, which would require changes in the poms) from: http://facelets.dev.java.net and install the missing artifact with mvn install:install-file -Dfile=el-api.jar -DgroupId=javax.el \ -DartifactId=el-api -Dversion=1.0 -Dpackaging=jar mvn install:install-file -Dfile=el-ri.jar -DgroupId=com.sun.el \ -DartifactId=el-ri -Dversion=1.0 -Dpackaging=jar This arifact requires the tobago-core-sources.jar artifact. The tobago-core-sources.jar is generated with the profile attach-source in core (mvn -P attach-source) or with the profile all-modules (mvn -P all-modules).
