Summary

  • Replace the hardcoded "!!! Unable to restart the IEHS App !!!" RuntimeException in AntExecutor (a stale boilerplate string from the file's borrowed srccodes.com template) with the actual BuildException message so the failure is clear.
  • Tee System.out/System.err during the Ant build and, on failure, scan the captured output for server-error markers (Response message from server is:, Server Detailed Error Message:, Server returned HTTP response code:) and append them to the thrown exception message. This surfaces the JSON body returned by the build server (which the build client prints to stdout but never propagates via the exception chain).
  • Console output is still forwarded to the original streams, so the user-visible build log is unchanged.
  • Add AntExecutorTest covering the marker extraction.

Motivation

A Maven Android build that hit a server-side HTTP 500 on /appsec/7.0/build/upload produced this misleading error:

Failed to execute goal ... !!! Unable to restart the IEHS App !!!

while the relevant detail — {"timestamp":"...","status":500,"error":"Internal Server Error","path":"/appsec/7.0/build/upload"} — was visible only earlier in the log and not in the exception message.

Test plan

  • mvn test -Dtest=AntExecutorTest — passes (3/3).
  • mvn compile for codenameone-maven-plugin — clean.
  • Reproduce with a triggered server build failure and confirm the response JSON shows up in the Maven failure message.

maven: surface real Ant/server error in AntExecutor failures
ef4ad75 
The catch-all in AntExecutor threw a hardcoded "Unable to restart the
IEHS App" RuntimeException for every BuildException, masking the actual
cause. When a server build fails (e.g. an HTTP 500 from the build
server) the build client prints the response body and JSON error to
stdout but does not propagate it through the exception chain, so the
maven user only saw the misleading message.

Tee stdout/stderr while the Ant project runs, scan the captured output
for the server-error markers ("Response message from server is:",
"Server Detailed Error Message:", "Server returned HTTP response
code:") and include them in the thrown RuntimeException's message
alongside the underlying BuildException's message. Console output is
still forwarded to the original streams so the user-visible build log
is unchanged.
