Directory structure of elasticsearch-java-8.0.0-SNAPSHOT.jar contains /./

[sothawo]

Not sure if this is an issue with the generated code, my IntelliJ setup or perhaps a bug in IntelliJ I am using the current version 2021.1.1).

I just want to write the code to create a SearchRequest.Builder and add some values.

When I have entered

SearchRequest.Builder builder = new SearchRequest.Builder();
builder.i

just after entering the i after the period, when IntelliJ IDEA is starting to autocomplete, the UI freezes and in the IntelliJ logs I can see, that the JVM is running out of heap space. Happens on two machines, the first has IDEA configured with 8GB heap, the second with 16GB.

Is this working for other people using IntelliJ IDEA?

After JetBrains had a look at this issue they found that the directory structure of the elasticsearch-java-8.0.0-SNAPSHOT.jar is somewhat strange:

$ jar tf elasticsearch-java-8.0.0-SNAPSHOT.jar.bak | head
META-INF/
META-INF/MANIFEST.MF
META-INF/./
META-INF/./LICENSE.txt
META-INF/./NOTICE.txt
co/
co/elastic/
co/elastic/clients/
co/elastic/clients/util/
co/elastic/clients/util/Union3$Tag.class

The license and notice file are in a subdirectory named /./. This causes IntelliJ to run into a recursion.

I extracted all the files and repackaged them so that the directory structure now is:

 jar tf elasticsearch-java-8.0.0-SNAPSHOT.jar | head
META-INF/
META-INF/MANIFEST.MF
META-INF/NOTICE.txt
META-INF/LICENSE.txt
co/
co/elastic/
co/elastic/clients/
co/elastic/clients/util/
co/elastic/clients/util/Union3$Tag.class
co/elastic/clients/util/QuadConsumer.class

With this I have no problems anymore with the code completion.

Is this a bug in the setup how the jar file is built?
