Soren Daugaard created TIKA-3035:
------------------------------------
Summary: Tika-app --extract mode outputs to stderr instead of
stdout
Key: TIKA-3035
URL: https://issues.apache.org/jira/browse/TIKA-3035
Project: Tika
Issue Type: Bug
Components: app
Affects Versions: 1.23
Reporter: Soren Daugaard
Attachments: testPDF_childAttachments.pdf
In version 1.23 of Tika I am noticing a problem using the extract
functionality. When extracting items from a file the "Extracting ... to ... "
output goes to {{stderr}} instead of {{stdout}}.
This problem is observed using the runnable jar `tika-app-1.23.jar` .
_*Example to re-create problem:*_
Here we explode {{testPDF_childAttachments.pdf}} and redirects standard error
to /{{dev/null}}:
{code:java}
$ java -jar tika-app-1.23.jar --extract-dir=tika-test/out/ -z
testPDF_childAttachments.pdf 2> /dev/null
{code}
If I do not redirect to stderr I see:
{code:java}
$ java -jar tika-app-1.23.jar --extract-dir=tika-test/out/ -z
testPDF_childAttachments.pdf
INFO As a convenience, TikaCLI has turned on extraction of
inline images for the PDFParser (TIKA-2374).
Aside from the -z option, this is not the default behavior
in Tika generally or in tika-server.

WARNING: Tesseract OCR is installed and will be automatically applied to image
files unless
you've excluded the TesseractOCRParser from the default parser.
Tesseract may dramatically slow down content extraction (TIKA-2359).
As of Tika 1.15 (and prior versions), Tesseract is automatically called.
In future versions of Tika, users may need to turn the TesseractOCRParser on
via TikaConfig.
