Error with Metadata Crawler

Anonymous — Fri, 02 Jun 2017 14:07:23 GMT

Hello

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 https://community.talend.com/t5/Design-and-Development/Getting-error-JVM-setup-is-similar-to-the-studio-while-running/m-p/25179). Is there anything wrong with my installed JRE's (see screenshot below)?

Installed JREs

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: https://github.com/talend-spatial/workspace-metadata-crawler

Hope it helps to debug the error.

Hello,

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

Hi,

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?
