Bazel unable to read .properties file.

[Kehinde Adeoya]

I have tried all suggested ways in the Bazel book/documentation online, and all other forum resources to configure it to work with loading .properties file but none has worked so far.  It  is a simple config.properties file. When I run the BUILD file , it returns file not found exception. 

load("@rules_java//java:defs.bzl", "java_test")

java_test(
name = "testng_integration",
args=["/Users/user/Documents/project/Bench/MultiLangTestFramework/WebPOM/src/test/resources/testrunners/testng_regressions.xml"],
data=["testng_regressions.xml",
"//WebPOM/src/test/resources/config:config_properties"],
resources = ["//WebPOM/src/test/resources/config:config_properties"],
main_class="org.testng.TestNG",
runtime_deps = [
"//WebPOM/src/main/java/com/qa/opencart/listeners:extent_report_listener",
"//WebPOM/src/test/java/com/qa/opencart/tests:login_steps",
"//WebPOM/src/test/java/com/qa/opencart/base:base_test",
"@maven//:org_apache_logging_log4j_log4j_slf4j_impl",
],
use_testrunner=False,
visibility = ["//visibility:public"],
)

All help would be appreciated.

[David Turner]

Your Java exception shows that the program tries to find "./src/test/resources/config/config.properties" in the current directory, which happens to be a sandbox populated by `bazel test` based on the content of `runtime_deps`.

This attribute does not list this file, which appears in `resources` instead. I believe the latter is only used to ensure the file is embedded in the .jar file instead.
Maybe adding the file to `runtime_deps` will solve it, or find a way for your test program to read it from its own resource pool instead?

Thanks for the answer. I have tried all possible suggestions in the books/forums to no avail, including the one you suggested now. 

[Gunnar Wagenknecht]

Resources from the class path should be loaded with with the ClassLoader.getResourceAsStream method. You need to inspect the jar file at which location Bazel puts it. There is some default stripping implement. You can override it with resource_strip_prefix.

Data files can be accessed from the file system. Did you try the data attribute?

I have attached the whole project. I really need help in this case. It's been over a week I have been on to run this simple PoC. How do I inpsect "the jar file at which location Bazel puts it"? I'm a newbie to Bazel.
