Error with Metadata Crawler


I am using TOS 6.3.1 with the metadata crawler workspace for TOS 6.x. My metadata crawling run crashed with the following error message:


Ausführung fehlgeschlagen: Job compile errors
At least job "scan_map_qgis" has a compile errors, please fix and export again.
Error Line: 21184
Detail Message: root_12_0_1_tAFOX_3 cannot be resolved to a variable

There may be some other errors caused by JVM compatibility. Make sure your JVM setup is similar to the studio.


I am aware that the last line is a kind of default message I get after all errors (see Is there anything wrong with my installed JRE's (see screenshot below)?

Other questions: I'd like to check the code but where do I find 'line 21184'? Has anyone an idea what 'root_12_0_1_tAFOX_3' could mean or come from?

Hi @ckampichler, you can find the source code under:

Hope it helps to debug the error.

Re: Error with Metadata Crawler


So far, talend don't support for openJDK. Have you tried to use oracle JDK 1.8 to see if your job works?

Best regards

Re: Error with Metadata Crawler


I installed the oracle JDK 1.8 as suggested by @xdshi but the error remains the same.

Since the error occurred in scan_map_qgis 0.1 I also tried to scan a raster file with scan_raster 0.1 instead of using run 0.1 . At first sight, this seems to work without error (except about the PNG driver):

The overview png is produced without problems, but the metadata xml-file is empty (0 bytes).

I tried also to scan a shape file with run_vector 0.1, but with the same result: the two xml-files (iso19110 and iso19139) are generated but are empty.

Any hints?
