Para-search-elasticsearch: NoSuchFieldError: LUCENE_8_3_0

[pikrakpzu]

Hi,

I`m trying to setup para with mongodb and elasticsearch for scoold pro on docker.

Mongodb + para + scooldPro works well.
After moving shaded para-search-elasticsearch jar to /para/lib, the para app can't start.
Docker run and log: para.log

Everything is managed by docker-compose, scoold-test_internal is a network for mongo/elasticsearch/scoold.
Para was moved out for testing, while ran with docker compose there was the same result.

Docker file for my/para:

FROM erudikaltd/para:v1.34.3
COPY --from=erudikaltd/para-dao-mongodb:1.34.0 /para/lib/* /para/lib/
COPY --from=erudikaltd/para-search-elasticsearch:1.34.1 /para/lib/* /para/lib/

Build:

docker build -f Dockerfile-para-plugins -t my/para:v1.34.3 .

You might want to downgrade ES to 7.5.1 because the para-search-elasticsearch plugin uses that version of the ES client. Usually such errors appear when the version of the client is older than that of the server. I'm not 100% sure though...

[albogdano]

Actually, I was wrong - ignore the comment above. You should extend erudikaltd/para:v1.34.3-base which is the Para container without any plugins in it. Otherwise you will have two different Lucene versons on the classpath as Para contains the para-search-lucene plugin.

Thanks for fast response.

I've ran para without para-search-elasticsearch-1.34.1-shaded.jar and it's up without any problems.
But on GET http://localhost:37988/v1/_setup it looks like there is no search implementation:

[ERROR] API request error:
java.lang.UnsupportedOperationException: Not implemented.

Full stack: para2.log

[albogdano]

That means that the plugin is not loaded or the property para.search = "ElasticSearch" is not in the Para configuration file.

[albogdano]

Try editing the dockerfile:

FROM erudikaltd/para:v1.34.3-base
COPY --from=erudikaltd/para-dao-mongodb:1.34.0 /para/lib/* /para/lib/
COPY --from=erudikaltd/para-search-elasticsearch:1.34.1 /para/lib/* /para/lib/

Then rebuild the whole container.

While running image based on para...-base only one log line is printed:
para_1 | no main manifest attribute, in para-base-1.31.4-SNAPSHOT.jar :)

[albogdano]

Oh, apparently the base package build is broken. I'll have to fix this...

[pikrakpzu]

Ok, so I'll wait for fix then.
