err, webview doesn't build anything under chrome/renderer I hope

try touching any .cc file under android_webview/common in step 2

doh! Yeah, pasted the wrong path there. It was a file in android_webview/ that I had touched to test this.

Fix is here: https://codereview.chromium.org/2091303002/

with that CL, it seems somethings are rebuilt even if I don't touch anything.. says it executed 142 steps for system_webview_apk

definitely better than wrong build though

Just tried typing "ninja system_webview_apk" twice in a row, and the second time it reported: ninja: no work to do.

If that's not the case, there's probably some other bug going on.

my args.gn:
"""
target_os = "android"
target_cpu = "arm"
dcheck_always_on = true
is_debug = false
is_component_build = true
is_clang = true
symbol_level = 1
system_webview_package_name = "com.google.android.webview"

run_findbugs = false

use_goma = false
"""

synced to r401888, ie past the fix, and building now, let's see after it builds..

that's weird, first clean build did 50 steps, then subsequent ones are "no work to do"..

and now I can't repro it at all on r401888, so nevermind..

original bug is fixed
