Description
I'm trying to precompile my assets by creating a ruby_binary that runs rake assets:precompile.
I intend to then tar up the compiled assets and have the genrule output these (rather than test.txt!)
My BUILD goes like this:
ruby_library(
name = "assets_precompile_lib",
srcs = glob(
include = [
"app/**/*",
"config/**/*",
"lib/**/*",
"vendor/assets/**/*",
],
) + [
"Rakefile"
],
deps = [
"@bundle//:gems",
],
)
ruby_binary(
name = "assets_precompile_bin",
srcs = [":assets_precompile_lib"],
args = ["assets:precompile"],
includes = [
"src/webapp/Rakefile",
],
main = "@bundle//:bin/rake",
deps = ["@bundle//:gems"],
)
genrule(
name = "test",
srcs = ["Rakefile"],
outs = ["test.txt"],
cmd = """
$(location :assets_precompile_bin)
echo "test" > $@
""",
local = 1,
message = "test",
tools = [
":assets_precompile_bin",
],
visibility = ["//visibility:public"],
)
But when I run the genrule I get:
➜ bazel build //src/webapp:test
INFO: Analyzed target //src/webapp:test (1 packages loaded, 1740 targets configured).
INFO: Found 1 target...
ERROR: /Users/robert.gates/Repositories/cube/src/webapp/BUILD:698:8: test //src/webapp:test failed: (Exit 1): bash failed: error executing command /bin/bash -c ... (remaining 1 argument skipped)

No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)

(See full trace by running task with --trace)
Target //src/webapp:test failed to build
Use --verbose_failures to see the command lines of failed build steps.
Could anyone help me understand what's wrong here? I've included the Rakefile in the lib, and also tried getting it onto the LOAD_PATH with includes = but no luck. Any advice really appreciated!
