The problem of java api download

[caos96]

I tried to obtain the Java API through the Maven settings provided at Aspose.CAD Java 24.4 | CAD and BIM Processing Conversion Java API SDK, but I was unable to do so, so I am reaching out for assistance.
How can I test the Java API?
Additionally, do I need a license for the free trial?

@caos96

Can you please specify what issues you encountered while trying to download the Java API through Maven? Also, are you asking about testing the API functionality or the installation process?

[caos96]

The library is not downloading from Maven. If the installation succeeds, I want to check the feasibility of adoption through a sample program, but I haven’t been able to install it yet, so I haven’t been able to do that.

@caos96,
Hello.
Just tested the pom.xml sample and see no issues with Maven. Please share the error you observe on your side. You can download the library directly also here (please see Package Explorer tab) or by your reference above (please look at Versions tab). You can obtain free evaluation license via Temporary License - Purchase - aspose.com to unlock all features of the product, or you can use it without license with limitations (watermark will appear, only 100 of entities are available to process with API).

@caos96,
please share the initial file so we can reproduce this issue.

[caos96]

TEST.zip (306.0 KB)

DWF and DWG, along with a Java file, are attached.

Thank you.

[snazeer]

am also facing this issue , just load image throws , any fix for this?

[caos96]

Could you please upload a DWG or DWF file that works?

[oleksii.gorokhovatskyi]

@snazeer, @caos96,
could you please check if switching to previous versions 24.3 or 24.2 resolves the issue?

[caos96]

wow! 24.2 work fine!
Thank you~!

[oleksii.gorokhovatskyi]

@caos96,
and what about 24.3? Does it fail there?

[caos96]

24.3 alose fine~

[oleksii.gorokhovatskyi]

@caos96,
could you please share what is your IDE? We have created CADJAVA-11697 to investigate this case.
