How To Use

A brief overview of how to use LSP4J to implement a server or a client can be found here:

• Getting Started
• Core Concepts

Maven Repositories

• Maven Central: https://repo.maven.apache.org/maven2/

p2 Update Sites

• Releases: https://download.eclipse.org/lsp4j/updates/releases/
• Milestones: https://download.eclipse.org/lsp4j/updates/milestones/
• Nightly: https://download.eclipse.org/lsp4j/builds/main/

japicmp reports

• The p2 Update sites listed above (since 0.13.0) contain a japicmp report against the last released version to make it easier to identify API changes.

Snapshots

The snapshots are deployed during the build to:

• https://oss.sonatype.org/content/repositories/snapshots/org/eclipse/lsp4j/

Signed JARs

The Maven Repositories, p2 Update Sites, and the Snapshots contain signed jars. If you plan to simply add them to your own jar, you'll need to remove/exclude or update/override these signatures.
