Ivy scan fails when ivy.jar is missing

[lampham-nttdata]

Hi guys,

I'm trying to use component-detection to scan Ant + Ivy projects, but encounter the following issue when running on an environment with ant and jdk installed:

[17:53:13 INF] Finding components...
[17:53:13 INF] No instructions received to scan docker images.
[17:53:13 INF] Preparing Rust component detection

[17:53:13 INF] Processing /ivy-demo/ivy.xml.
[17:53:14 ERR] Ant command failed with return code 1
[17:53:14 WRN] Ant command stderr:
BUILD FAILED
/tmp/vule5dto.uz1/build.xml:11: Compile failed; see the compiler error output for details.

But when I add ivy.jar into directory .ant/lib, the scan works fine.
According to Ivy Detection, I don't see ivy.jar is mentioned, but based on the way Ivy Detection works with IvyComponentDetectionAntTask.java I believe ivy.jar is mandatory.
