-------------------------------
Resolution: Fixed
> tika-app-4.0.0-alpha1 - image extraction fails when using --extract
> -------------------------------------------------------------------
>
> Key: TIKA-4736
> URL: https://issues.apache.org/jira/browse/TIKA-4736
> Project: Tika
> Issue Type: Bug
> Reporter: Adrian Bird
> Priority: Major
>
> Using -z works:
> {code:java}
> %JAVA_HOME%\bin\java -jar %TIKA_JAR% -z --extract-dir=ImageFiles
> MyTestFile.pdf {code}
> Using --extract fails:
> {code:java}
> %JAVA_HOME%\bin\java -jar %TIKA_JAR% --extract --extract-dir=ImageFiles
> MyTestFile.pdf
> Exception in thread "main" org.apache.tika.exception.TikaConfigException:
> Can't have more than 2 unknown args: [--extract, -o, ImageFiles,
> MyTestFile.pdf]{code}
> If I change the order I get a different error:
> {code:java}
> %JAVA_HOME%\bin\java -jar %TIKA_JAR% --extract-dir=ImageFiles --extract
> MyTestFile.pdf
> Exception in thread "main" org.apache.tika.exception.TikaConfigException: Can
> only set inputDir and outputDir once. Extra args: [--extract, MyTestFile.pdf]
> {code}
>
> I also noticed that V4 produces an error if you do the extraction more than
> once, saying the image files already exist, where V3 created multiple files.
