# Build System Changes for Android.mk Writers
## Genrule starts disallowing directory inputs
To better specify the inputs to the build, we are restricting use of directories
as inputs to genrules.
To fix existing uses, change inputs to specify the inputs and update the command
accordingly. For example:
```
genrule: {
name: "foo",
srcs: ["bar"],
cmd: "cp $(location bar)/*.xml $(gendir)",
...
}
```
would become
```
genrule: {
name: "foo",
srcs: ["bar/*.xml"],
cmd: "cp $(in) $(gendir)",
...
}

with genrules that have input directories.
