Example 71 with BuildException

use of org.apache.tools.ant.BuildException in project gate-core by GateNLP.

the class PackageGappTask method getUnresolvedResourcesTarget.

/**
 * Get a URL for a directory to which the given (unresolved) resource
 * directory should be mapped.
 *
 * @param unresolvedResourcesSubDirs a map from URLs of directories
 *          containing unresolved resources to the URLs under the
 *          target unresolved-resources directory that they will be
 *          mapped to. This map is updated by this method.
 * @param unresolvedResourcesDir the top-level application-resources
 *          directory in the target location.
 * @param resourceDir a directory containing an unresolved resource.
 * @return the URL under application-resources to which this directory
 *         should be mapped. For a resourceDir of the form .../foo,
 *         the returned URL would typically be
 *         <applicationResourcesDir>/foo, but if a different
 *         directory with the same name has already been mapped then
 *         we will return the first ..../foo-2, foo-3, etc. that is
 *         not already in use.  If one of the directory's ancestors
 *         has already been mapped then we return a URL pointing
 *         to the same relative path inside that ancestor's mapping,
 *         e.g. if .../foo has already been mapped to a-r/foo-2 then
 *         .../foo/bar/baz will map to a-r/foo-2/bar/baz.
