        Specified by:
        getDependencies in interface ITemplateSection
        Parameters:
        schemaVersion - version of the target manifest, or null if older manifest (prior to 3.0) will be created. Depending on the manifest version, the list of dependencies may vary.

      • getSourceFolder

        protected IFolder getSourceFolder​(IProgressMonitor monitor)
        Returns the folder with Java files in the target project. The default implementation looks for source folders in the classpath of the target folders and picks the first one encountered. Subclasses may override this behaviour.
        Parameters:
        monitor - progress monitor to use
        Returns:
        source folder that will be used to generate Java files or null if none found.
      • generateFiles

        protected void generateFiles​(IProgressMonitor monitor,
                                     URL locationUrl)
                              throws CoreException
        Generates files as part of the template execution. The files found in the location are processed in the following way:
        • Files and folders found in the directory bin are copied into the target project without modification.
        • Files found in the directory java are copied into the Java source folder by creating the folder structure that corresponds to the package name (variable packageName ). Java files are subject to conditional generation and variable replacement.
        • All other files and folders are copied directly into the target folder with the conditional generation and variable replacement for files. Variable replacement also includes file names.
        Parameters:
        monitor - progress monitor to use to indicate generation progress
        locationUrl - a url pointing to a file/directory that will be copied into the template
        Throws:
        CoreException
        Since:
        3.3
      • isOkToCreateFolder

        protected boolean isOkToCreateFolder​(File sourceFolder)
        Tests if the folder found in the template location should be created in the target project. Subclasses may use this method to conditionally block the creation of entire directories (subject to user choices).
        Parameters:
        sourceFolder - the folder that is tested
        Returns:
        true if the provided folder should be created in the workspace, false if the values of the substitution variables indicate otherwise.
      • isOkToCreateFile

        protected boolean isOkToCreateFile​(File sourceFile)
        Tests if the file found in the template location should be created in the target project. Subclasses may use this method to conditionally block creation of the file (subject to user choices).
        Parameters:
        sourceFile - the file found in the template location that needs to be created.
        Returns:
        true if the specified file should be created in the project or false to skip it. The default implementation is true .

                     throws CoreException
        The default implementation of the interface method. It will generate required files found in the template location and then call updateModel to add the required manifest entires.
        Specified by:
        execute in interface ITemplateSection
        Parameters:
        project - the workspace project that contains the plug-in

                                         String value)
        Sets a header within the plug-in's underlying manifest header, if it has one. It the plug-in doesn't have a manifest, this method does nothing. It's expected that this method will only be called by sub-classes during execution of the template (i.e. during the sub-class's updateModel(...) method).

        For example:

        setManifestHeader(Constants.BUNDLE_LOCALIZATION, "plugin")
        Parameters:
        name - The name of the header to set
        value - The value of the header

      • getManifestHeader

        protected String getManifestHeader​(String name)
        Gets a header from within the plug-in's underlying manifest header, if it has one. If the plug-in doesn't have a manifest, this method returns null. It's expected that this method will only be called by sub-classes during execution of the template (i.e. during the sub-class's updateModel(...) method).
        Parameters:
        name - The name of the header to fetch
        Returns:
        The value of the manifest header, if available, otherwise null
        Since:

      • hasBundleManifest

        protected boolean hasBundleManifest()
        Determines whether this plug-in has a manifest on which to set/get headers. This method will return false if the plug-in doesn't have a manifest (e.g. it's a v3.0 plug-in) or if the method is called before the model has been set on the template. It's expected that this method will only be called by sub-classes during execution of the template (i.e. during the sub-class's updateModel(...) method).
        Returns:
        true if the plug-in has a manifest, false otherwise
