Class TestSchemaGenerationMojo

  • All Implemented Interfaces:
    org.apache.maven.plugin.ContextEnabled, org.apache.maven.plugin.Mojo

    @Mojo(name="testSchemagen",
          defaultPhase=GENERATE_TEST_RESOURCES,
          requiresDependencyResolution=TEST,
          threadSafe=true)
    public class TestSchemaGenerationMojo
    extends AbstractXsdGeneratorMojo

    Mojo that creates XML schema(s) from test-scope Java testSources or binaries by invoking the JAXB SchemaGenerator. This implementation is tailored to use the JAXB Reference Implementation from project Kenai.

    Note that the TestSchemaGenerationMojo was completely re-implemented for the 2.x versions. Its configuration semantics and parameter set is not backwards compatible with the 1.x plugin versions. If you are upgrading from version 1.x of the plugin, read the documentation carefully.

      • STANDARD_TEST_SOURCE_EXCLUDE_FILTERS

        public static final java.util.List<Filter<java.io.File>> STANDARD_TEST_SOURCE_EXCLUDE_FILTERS

        Default exclude file name suffixes for testSources, used unless overridden by an explicit configuration in the testSchemaSourceExcludeFilters parameter. The default values are found as follows:

             
                 final List<Filter<File>> testSrcTemp = new ArrayList<Filter<File>>();
                 testSrcTemp.addAll(AbstractJaxbMojo.STANDARD_EXCLUDE_FILTERS);
                 testSrcTemp.add(new PatternFileFilter(Arrays.asList("\\.xjb", "\\.xsd", "\\.properties"), true));
                 STANDARD_TEST_SOURCE_EXCLUDE_FILTERS = Collections.unmodifiableList(testSrcTemp);

      • testSources

        @Parameter(required=false)
        private java.util.List<java.lang.String> testSources

        Parameter holding List of paths to files and/or directories which should be recursively searched for Java source files. Only files or directories that actually exist will be included (in the case of files) or recursively searched for source files to include (in the case of directories or JARs). Configure using standard Maven structure for Lists:

         
           <configuration>
           ...
               <testSources>
                  <testSource>/a/full/absolute/path/to/a/SourceFile.java</testSource>
                  <testSource>target/some/sourceJar.jar</test>
                  <testSource>src/test/java</test>
              </testSources>
           </configuration>
         
         

        Note: if configured, the sources parameters replace the default value, which is a List containing the paths to the directories defined by getProject().getTestCompileSourceRoots().

      • testSchemaSourceExcludeFilters

        @Parameter(required=false)
        private java.util.List<Filter<java.io.File>> testSchemaSourceExcludeFilters

        Parameter holding a List of Filters, used to match all files under the testSources directories which should not be considered SchemaGenerator testSource files. (The filters identify files to exclude, and hence this parameter is called testSchemaSourceExcludeFilters). If a file under any of the testSource directories matches at least one of the Filters supplied in the testSchemaSourceExcludeFilters, it is not considered an XJC test source file, and therefore excluded from processing.

        If not explicitly provided, the Mojo uses the value within STANDARD_TEST_SOURCE_EXCLUDE_FILTERS. The algorithm for finding XJC sources is as follows:

        1. Find all files given in the testSources List. Any Directories provided are searched for files recursively.
        2. Exclude any found files matching any of the supplied testSchemaSourceExcludeFilters List.
        3. The remaining Files are submitted for processing by the XJC tool.

        Example: The following configuration would exclude any testSources whose names end with .txt or .foo:

             
                 <configuration>
                 ...
                      <testSchemaSourceExcludeFilters>
                          <filter implementation="org.codehaus.mojo.jaxb2.shared.filters.pattern.PatternFileFilter">
                              <patterns>
                                  <pattern>\.txt</pattern>
                                  <pattern>\.foo</pattern>
                              </patterns>
                          </filter>
                      </testSchemaSourceExcludeFilters>
                 </configuration>
             
         

        Note that inner workings of the Dependency Injection mechanism used by Maven Plugins (i.e. the DI from the Plexus container) requires that the full class name to the Filter implementation should be supplied for each filter, as is illustrated in the sample above. This is true also if you implement custom Filters.

        @Parameter(defaultValue="${project.build.directory}/generated-test-resources/schemagen",
                   required=true)
        private java.io.File outputDirectory

        The directory where the generated XML Schema file(s) will be placed.

                   required=true)
        private java.io.File testWorkDirectory

        The directory where the schemagen tool will output XSDs, episode files - and intermediary bytecode files. From this directory the XSDs and the episode file (but not the bytecode files) will be copied to the outputDirectory for further processing.

        protected void addResource​(org.apache.maven.model.Resource resource)
        Adds the supplied Resource to the project using the appropriate scope (i.e. resource or testResource) depending on the exact implementation of this AbstractJaxbMojo.
