lsif-java v0.6.4

Scala support

It's now possible to index Scala code with lsif-java. For example, this link shows you references to the java.lang.String.split() method from the Scala standard library, Spark and MUnit. The versions Scala 2.11.x, 2.12.x, 2.13.x and 3.x are supported.

sbt support

Previously, only the build tools Gradle and Maven were supported for the lsif-java index command. Now, you can also run lsif-java index in sbt projects. Both Java and Scala sources will be indexed.

For example, you can now use precise code intelligence on Sourcegraph.com to browse the akka/akka and haifengl/smile repositories.

• https://sourcegraph.com/github.com/akka/akka/-/blob/akka-actor/src/main/java/akka/actor/dungeon/AbstractActorCell.java?L10:13#tab=references
• https://sourcegraph.com/github.com/haifengl/smile/-/blob/core/src/main/java/smile/validation/metric/Specificity.java?L36:14#tab=references

Observe that "find references" shows results in both Java and Scala sources.

⚠️ Caveats

The lsif-java index command does not yet support Scala projects using the build tools Maven or Gradle. Subscribe to #301 to get notified when we add support for Scala Maven projects and #302 when we add support for Scala Gradle projects.

lsif-java v0.5.7

Rework emitted packageInformation vertex data

Previously, lsif-java included the library version in the name field of the packageInformation vertices. This releases changes this to only include the version info in the version field for consistency with other LSIF indexers.
The manager field is also changed to no longer have the value "packagehub". This was a temporary value during lifetime of the POC of PackageHub, which has been replaced by a new External Service type.

lsif-java v0.5.6

Improved error handling

Previously, the lsif-semanticdb command could fail with an exception when processing certain SemanticDB files. This release includes improvements to error handling so that lsif-semanticdb should fail less frequently, and it should report a more helpful error message in the cases where it still fails.

lsif-java v0.5.5

Improved ANSI color output

Previously, lsif-java used default color output settings when shelling out to Maven and Gradle. Now, lsif-java uses --batch-mode for Maven and TERM=dumb for Gradle to reduce ANSI color output (helpful for CI logs). Additionally, the NO_COLOR=true environment variable is respected so that you can disable all ANSI color output.

lsif-java v0.5.4

Use kind: local for local symbols

Use "local" instead of "import" for local symbol monikers. (#228) @olafurpg. This should help reduce storage size on Sourcegraph

lsif-java v0.5.3

Improved cross-repo navigation

Previously, cross-repo navigation would frequently fail to work, in particular when navigating to symbols from the JDK. This release includes several fixes so that cross-repo navigation should in general work more reliably now.

New -targetroot:javac-classes-directory

Thanks to a contribution from @wiwa, it's possible to configure the semanticdb-javac compiler plugin to emit SemanticDB files in the same directory where the compiler emits classfiles. This makes it easier to integrate lsif-java with a build tool since you can use the same -targetroot:javac-classes-directory for all projects/modules in a build. Previously, it was necessary to provide an explicit directory for every project/module.

lsif-java v0.5.0

We are excited to announce the v0.5.0 release of lsif-java 🚀

Installing

Use Coursier to install lsif-java.

cs install --contrib lsif-java

Upgrading

To upgrade to the latest release, run

cs upgrade lsif-java

Improved hover messages

Hover messages now include the full signature of the definition symbol, including annotations.

NOTE: currently, hover messages only render signatures that are defined in the local repository. Subscribe to #174 for updates on rendering signatures of external symbols that are defined outside of the local repository.

Gradle improvements

The lsif-java index command should work now with the Playframework plugin for Gradle or the newly released Gradle v7.0.

First step towards navigation for Java libraries

The generated LSIF data now includes packageInformation nodes to link to externally defined symbol. This is the first step towards enabling cross-repository navigation. The next step will be to extend the Sourcegraph backend to serve published Java libraries from Maven Central.

Visit this link to see a live demo of this functionality. The link points to the sources of the Guava library. Observe that you can navigate to symbols that are defined in the JDK, and you can also "find references" can show results from multiple repositories.

Multiple navigation improvements

Goto definition and find references should work better across the board. To name a few changes

• goto definition on a constructor now goes straight to the constructor instead of the class symbol
• goto definition on anonymous classes should give more reliably accurate results
• find references no longer includes confusing references to this

lsif-java v0.3.0

🚀 New LSIF emitter

Previously, lsif-java had a system dependency on a separate tool called lsif-semanticdb in order to work. This dependency has now been removed so that installing lsif-java is the only custom tool you need available on your $PATH

• Implement LSIF emitter in Java. (#127) @olafurpg

🚧 Progress towards better hover messages

Currently, hover messages only contain Javadoc docstrings. We're working on extending hover messages to also include signatures of the referenced symbol. This functionality is planned for the next release once the PR #131 is merged.
