I am normally not answering my own questions. But for now I came up with following solution:<\/p>\n

I am marking my strings as follows in an additional comment (I know not DRY anymore):<\/p>\n

\/\/_.trans(\"Please enter a valid string\");\n@NotNull(message=\"Please enter a valid string\")\nString string;\n<\/code><\/pre>\n
I am calling following script in my pom:<\/p>\n
#!\/bin\/bash\n\n# $1 -> java source directory\n# $2 -> output file\n# $3 -> po directory\n\necho \"Source Directory: $1\"\necho \"Keys File: $2\"\necho \"PO Directory: $3\"\n\nxgettext --from-code utf-8 -L Java --force-po -ktrc:1c,2 -ktrnc:1c,2,3 -ktr -kmarktr -ktrn:1,2 -k -o \"$2\" $(find \"$1\" -name \"*.java\")\nsed \"s\/\\\/\\\/_\/_\/g\" $(find \"$1\" -name \"*.java\") | xgettext -F --from-code utf-8 -L Java -ktrans -k -j -o \"$2\" -\n\npofiles=$3\/*.po\nshopt -s nullglob\nfor i in $pofiles\ndo\n   echo \"msgmerge $i\"\n   msgmerge --backup=numbered -U $i $2\ndone\n<\/code><\/pre>\n
This script first calls xgettext normally and then calls sed to remove the comment slashes and pipes to xgettext. Thus I have all my keys in keys.pot.<\/p>\n

I know the build is not platform independent anymore but in a separate profile I can live with it. However, it works also on cygwin for the windows guys.<\/p>\n
My messageinterpolator is as follows:<\/p>\n
public class GettextMessageInterpolator implements MessageInterpolator {\n\n    private final MessageInterpolator delegate;\n\n    public GettextMessageInterpolator() {\n        this.delegate = new ResourceBundleMessageInterpolator();\n    }\n\n    @Override\n    public String interpolate(String message, Context context) {\n        return this.interpolate(message, context, ClientLocalLocator.get());\n    }\n\n    @Override\n    public String interpolate(String message, Context context, Locale locale) {   \n        I18n i18n = ClientLocalLocator.getI18n();\n        String retVal = i18n.tr(message);\n        if (StringUtils.isNotBlank(retVal))\n            return retVal;\n        return delegate.interpolate(message, context, locale);\n    }\n\n}\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
