  - Dockerfile:13
  - ERROR: failed to build: failed to solve: process "/bin/sh -c mvn -B -ntp -Dtoolchain.skip install -U -DskipTests=true" did not complete successfully: exit code: 1

Missing packages/files mentioned
- ~/.m2/toolchains.xml (toolchains definitions file)

Version mismatch / configuration details
- Toolchain issue: No toolchain found for type jdk, required toolchain: jdk [ version='25' ]
- Maven Toolchains plugin cannot find matching toolchain definitions for jdk version 25
- Suggests defining the required toolchains in ~/.m2/toolchains.xml
- Context: base image uses maven:3.9.14-sapmachine-25, but toolchains.xml definitions are missing or do not include JDK 25.
