Collector with custom plugins compilation broken

[lgtti]

Hi,

we are using our collector with contrib plugins using ocb.

The config file is the following:

dist:
  name: edge
  description: open telemetry collector with additional filelog receiver
  output_path: .
  otelcol_version: 0.99.0

receivers:
  - gomod:
      github.com/open-telemetry/opentelemetry-collector-contrib/receiver/filelogreceiver v0.99.0
  - gomod:
      github.com/open-telemetry/opentelemetry-collector-contrib/receiver/hostmetricsreceiver v0.99.0
  - gomod:
      go.opentelemetry.io/collector/receiver/otlpreceiver v0.99.0
processors:
  - gomod:
      go.opentelemetry.io/collector/processor/batchprocessor v0.99.0
  - gomod:
      github.com/open-telemetry/opentelemetry-collector-contrib/processor/resourceprocessor v0.99.0
  - gomod:
      go.opentelemetry.io/collector/processor/memorylimiterprocessor v0.99.0
exporters:
  - gomod:
      go.opentelemetry.io/collector/exporter/debugexporter v0.99.0
  - gomod:
      go.opentelemetry.io/collector/exporter/otlphttpexporter v0.99.0
  - gomod:
      github.com/open-telemetry/opentelemetry-collector-contrib/exporter/lokiexporter v0.99.0

These are the steps:

curl --proto '=https' --tlsv1.2 -fL -o src/ocb \
    https://github.com/open-telemetry/opentelemetry-collector/releases/download/cmd%2Fbuilder%2Fv0.99.0/ocb_0.99.0_linux_amd64

chmod +x src/ocb

GOFLAGS=-buildvcs=false ./ocb --config builder_config.yaml

We have successfully compiled it at 2024-07-30 in the morning and we have tried a new compilation yesterday (2024-10-17) with this error:

+ GOFLAGS=-buildvcs=false ./ocb --config builder_config.yaml

How is possible? The plugins, the ocb and base otel collector versions are the same but the compilation fails. This is a huge stability problems if the build version is not reproducible.

Is there a workaround or a bufix for this problem?
