Build failure after fixing a previous issue: DX returned an error code
Hi @ewpatton ,
Hope you're doing well.
Thank you for your last message. I managed to solve the previous build error (Java returned: 137) that I was stuck on.
However, after fixing that, I've now encountered a new build failure. The error message is DX returned an error code, which seems to be related to a multidex issue.
To fix it, I tried these steps:
- Running the
ant command with -Dappinventor.multidex=true
- Also adding the Java compiler flags
-Dbuild.compiler.source=1.6 -Dbuild.compiler.target=1.6 along with the multidex flag.
- I even tried adding
<property name="appinventor.multidex" value="true"/> directly to the buildserver/build.xml file.
Unfortunately, none of these attempts worked, and the build is still failing with the same error.
I tried to post the full error log, but it was too long and exceeded the character limit for new users on the forum.
I've pasted the most critical part of the log below. It contains the key errors at the end of the build process. If you need the full log, I can upload it to Google Drive and share the link.
Could you please help me with this?
Thanks, Muskan Kumari
