Java

To index Java we use lsif-java in LSIF mode from SourceGraph. This indexer supports Java, Kotlin and Scala indexing, however we have only tested with Java so far. Maven and Gradle are well supported.

You can download the latest lsif-java from Maven.org central. Example installation using coursier. You will need a JDK and Maven or Gradle installed to build, as lsif-java is a plugin to the Java compiler.

curl -fLo coursier https://git.io/coursier-cli && chmod +x coursier
./coursier bootstrap --standalone -o lsif-java com.sourcegraph:lsif-java_2.13:0.8.0-RC1 --main-class com.sourcegraph.lsif_java.LsifJava

Run the indexer​

The indexer can be run via the main glean CLI tool.

> cabal build exe:glean

And index your Java repository with:

glean index java-lsif DIR --db NAME/INSTANCE

where

  • DIR is the root directory containing the Rust project
  • name/hash is the name of the repository to create

Provide the usual --db-root and --schema or --service arguments to glean

In the shell​

Java source can also be indexed directly from the Glean shell:

:index java-lsif DIR

The shell will pick a DB name and hash for you based on DIR. You can also run lsif-java offline, and then :load the resulting lsif file into the shell.

Schema​

The schema is in glean/schema/source/lsif.angle
