Stefano, the app-schema resolver gives priority to schemas on the classpath over schemas downloaded and stored in the app-schema cache: http://docs.geoserver.org/latest/en/user/data/app-schema/app-schema-resolution.html
The gt-app-schema module includes several test dependencies that are jar files containing application schemas, built using these poms (and manually deployed to the osgeo Maven repository): https://github.com/geotools/geotools/tree/master/modules/extension/app-schema/app-schema-packages I will list these schema jars later in this email. By manually adding the gt-app-schema project to the GeoServer classpath rather than using Maven eclipse:eclipse (with the -Papp-schema profile) you are adding transitive dependencies and including test dependencies. Key differences between Maven and Eclipse are that Eclipse has no concept of phase (compile versus test) and no way of excluding transitive dependencies. Eclipse dependencies tend to be a superset of Maven dependencies. Maven dependency:tree with -Papp-schema inside GeoServer src/web/app includes only the following related to app-schema (no schema jars): [INFO] +- org.geotools:gt-app-schema:jar:14-SNAPSHOT:compile [INFO] | +- org.geotools:gt-complex:jar:tests:14-SNAPSHOT:compile [INFO] | +- commons-digester:commons-digester:jar:1.7:compile [INFO] | | \- xml-apis:xml-apis:jar:1.0.b2:compile [INFO] | +- org.geotools:gt-app-schema-resolver:jar:14-SNAPSHOT:compile [INFO] | \- xpp3:xpp3_min:jar:1.1.4c:compile Now compare with this excerpt (schema jars only) from Maven dependency:tree run inside GeoTools modules/extension/app-schema/app-schema; all these will be included by your Eclipse project dependency: [INFO] +- org.geotools.schemas:geosciml-2.0:jar:2.0.2-4:test [INFO] | +- org.geotools.schemas:gml-3.1:jar:3.1.1-4:test [INFO] | | \- org.geotools.schemas:xlink-1.0:jar:1.0.0-3:test [INFO] | +- org.geotools.schemas:sampling-1.0:jar:1.0.0-4:test [INFO] | | +- org.geotools.schemas:om-1.0:jar:1.0.0-4:test [INFO] | | | \- org.geotools.schemas:sensorML-1.0:jar:1.0.1-4:test [INFO] | | | \- org.geotools.schemas:ic-2.0:jar:2.0.0-3:test [INFO] | | \- org.geotools.schemas:sweCommon-1.0:jar:1.0.1-4:test [INFO] | \- org.geotools.schemas:cgiutilities-1.0:jar:1.0.0-4:test [INFO] +- org.geotools.schemas:earthresourceml-1.1:jar:1.1.0-3:test [INFO] +- org.geotools.schemas:xml-1.0:jar:1.0.0-3:test [INFO] +- org.geotools.schemas:geosciml-3.0-seegrid:jar:3.0.0-1:test [INFO] | +- org.geotools.schemas:gml-3.2:jar:3.2.1-1:test [INFO] | +- org.geotools.schemas:iso-19139-2007:jar:1.0.0-1:test [INFO] | +- org.geotools.schemas:iso-19156-seegrid:jar:2.0.0-1:test [INFO] | | +- org.geotools.schemas:om-2.0:jar:2.0.0-1:test [INFO] | | \- org.geotools.schemas:sampling-2.0:jar:2.0.0-1:test [INFO] | \- org.geotools.schemas:sweCommon-1.0-gml32:jar:1.0.1-1:test [INFO] +- org.geotools.schemas:geosciml-3.2:jar:3.2.0-1:test [INFO] | +- org.geotools.schemas:sweCommon-2.0:jar:2.0-1:test [INFO] | | \- org.geotools.schemas:xlink-1999:jar:1.0.0-1:test [INFO] | \- org.geotools.schemas:samplingSpatial-2.0:jar:2.0-1:test You have added to the Eclipse classpath jars that contain GML 3.2, GMD, a pre-release O&M 2.0 (iso-19156-seegrid), and Sampling, amongst others. The app-schema resolver will give these priority over anything it caches from the net, so you may be using these older Maven-cached versions of the schemas, not the latest ones from the net. Kind regards, Ben.
