rust - error: can't find crate -

i'm trying use this library.
but, cargo build says this:

   compiling test v0.1.0 (file:///c:/path/to/project/test) src\main.rs:1:1: 1:28 error: can't find crate `jvm_assembler` [e0463] src\main.rs:1 extern crate jvm_assembler;           ^~~~~~~~~~~~~~~~~~~~~~~~~~~ error: aborting due previous error not compile `test`.  learn more, run command again --verbose. 

my cargo.toml this:

[package] name = "test" version = "0.1.0" authors = ["yomizu_rai"]  [dependencies] jvm-assembler = "*" 

src/main.rs this, , there no other sourcefiles.

extern crate jvm_assembler; use jvm_assembler::*; fn main() {} 

i think cargo.toml not wrong, , src/main.rs has no room mistake.
why can not rustc find jvm-assembler?
how resolve?

cargo can find crates name if on crates.io. in case need specify git url, see section on dependencies in cargo documentation.
