[−][src]Crate java_locator
java-locator
This is a small utility written in Rust.
It locates the active Java installation in the host.
Usage
The utility can be used as a library, or as an executable:
Library
extern crate java_locator; fn main() -> java_locator::errors::Result<()> { let java_home = java_locator::locate_java_home()?; let dyn_lib_path = java_locator::locate_jvm_dyn_library()?; let libjsig = java_locator::locate_file("libjsig.so")?; println!("The java home is {}", java_home); println!("The jvm dynamic library path is {}", dyn_lib_path); println!("The file libjsig.so is located in {}", libjsig); Ok(()) }
Executable
Having rust installed, you may install the utility using cargo:
cargo install java_locator
And then, issuing
java-locator
you should have an output like:
/usr/lib/jvm/java-11-openjdk-amd64
You may retrieve the location of the jvm
shared library:
java-locator --jvmlib
should give an output like:
/usr/lib/jvm/java-11-openjdk-amd64/lib/server
This may be used in cases when the LD_LIBRARY_PATH
(or PATH
in windows) should be populated.
You may also retrieve the location of any file inside the Java installation:
java-locator --file libjsig.so
and you can even use wildcards:
java-locator --file libjsig*
The latter two commands should return something like:
/usr/lib/jvm/java-11-openjdk-amd64/lib
