How to set environment variable LD_LIBRARY_PATH through build.gradle to generate protobuf code - build.gradle

Question

I am using protobuf gradle plugin in my build.gradle file to
generate grpc and reactor gprc java code.
Due to the security constraints, I cannot use the plugin directly
from the maven central. I have to download those plugins and provide
the local path in my gradle file.
Unfortunately, while setting things locally, it seems that the
protoc compiler looks for LD_LIBRARY_PATH which we need to provide
explicitly.
Is there a way to set this path in gradle file?
Below is how I am using protobuf plugin
apply plugin: "com.google.protobuf"
protobuf {
protoc {
path = "Local protoc path"
}
plugins {
grpc {
path = "Local Protoc gen grpc path"
}
reactor {
path = "Local salesforce reactor grpc path
}
}
generateProtoTasks {
ofSourceSet("main")*.plugins {
grpc {}
reactor {}
}
}
}
Running above file gives below error
"error while loading shared libraries: libprotoc.so.15: cannot open shared object file: No such file or directory"
Looking for this error online shows that I need to set LD_LIBRARY_PATH

Answer 1

The protoc version on Maven Central is statically linked with libprotoc, so LB_LIBRARY_PATH would not be necessary. Use it instead. Note that the files must have a file extension, so they use the .exe file extension even on Linux. You can similarly download the grpc protoc plugin.
