Telegram – Can't use TDLight (TDLib fork) in Java

please help. 2 days wasted for this problem 🙁

I’m creating Telegram bot in Java using https://github.com/tdlight-team/tdlight.
I created Gradle project, built jar, and now trying to run it in Docker image FROM openjdk:17-alpine

Some important things from build.gradle:

buildscript {
    apply from: 'versions.gradle'
    repositories {
        mavenCentral()
        maven { url "https://plugins.gradle.org/m2/" }
        maven { url "https://mvn.mchv.eu/repository/mchv/" }
        jcenter()
    }
    dependencies {
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version")
        classpath("org.jetbrains.kotlin:kotlin-stdlib-common:$kotlin_version")
    }
}
plugins {
    id 'org.jetbrains.kotlin.jvm' version "$kotlin_version"
    id 'org.jetbrains.kotlin.plugin.serialization' version "$kotlin_version"
    id "com.github.johnrengelman.shadow" version '7.1.2'
}
dependencies {
//    implementation "org.telegram:telegrambots:${versions.telegram}"
    implementation platform("it.tdlight:tdlight-java-bom:${versions.tdLight}")
    implementation group: 'it.tdlight', name: 'tdlight-java', classifier: 'jdk8' // Java 8 is supported if you use the following dependency classifier: `jdk8`
//    implementation group: 'it.tdlight', name: 'tdlight-natives', classifier: 'linux_amd64_gcc_ssl1'
//    implementation group: 'it.tdlight', name: 'tdlight-natives', classifier: 'linux_amd64_gcc_ssl3'
    implementation group: 'it.tdlight', name: 'tdlight-natives', classifier: 'windows_amd64'
    implementation group: 'it.tdlight', name: 'tdlight-natives', classifier: 'linux_amd64_ssl1'
    implementation group: 'it.tdlight', name: 'tdlight-natives', classifier: 'linux_amd64_ssl3'

    implementation "com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:${versions.jackson}"
    implementation "com.fasterxml.jackson.core:jackson-databind:${versions.jackson}"
    implementation "com.sksamuel.hoplite:hoplite-core:${versions.hoplite}" //to read properties
    implementation "com.sksamuel.hoplite:hoplite-yaml:${versions.hoplite}" //to read yaml-properties

//...

kotlin {
    jvmToolchain(11)
}

compileKotlin {
    kotlinOptions.jvmTarget = '11'
}

compileTestKotlin {
    kotlinOptions.jvmTarget = '11'
}

jar {
    manifest {
        attributes 'Main-Class': 'name.nepavel.otus.watchbot.MainKt'
    }
}

shadowJar {
    archiveVersion.set(project.version)
}

Almost everything is exactly as in TDLight readme.md.
Then I connected to Docker container’s shell and run:
docker run -v D::/d -it --entrypoint /bin/sh --name open17 norg/openjdk-17

/ # java -version
openjdk version "17-ea" 2021-09-14
OpenJDK Runtime Environment (build 17-ea+14)
OpenJDK 64-Bit Server VM (build 17-ea+14, mixed mode, sharing)

java -jar /d/work/otus/repos/watchbot/build/libs/watchbot-1.0-SNAPSHOT-all.jar
And got a long stacktrace:

This means that precompiled natives are not accessible in my jar file. Then I decided to build tdjni native inside my Docker image. I took the build commands from here: https://tdlight-team.github.io/tdlight/build.html?language=Kotlin
and created the following Dockerfile:

FROM openjdk:17-alpine
ARG VER=$VER
ENV VER=$VER
ENV JAVA_OPTS=-Xmx1g
RUN echo "Version = $VER"
RUN echo "JAVA_HOME = $JAVA_HOME"

RUN apk update && 
    apk upgrade && 
    apk add --update alpine-sdk linux-headers git zlib-dev openssl-dev gperf php cmake openjdk8 && 
    git clone https://github.com/tdlight-team/tdlight.git && 
    cd tdlight && 
    rm -rf build && 
    mkdir build && 
    cd build && 
    cmake -DCMAKE_BUILD_TYPE=Release -DJAVA_HOME=/usr/lib/jvm/java-1.8-openjdk/ -DCMAKE_INSTALL_PREFIX:PATH=../example/java/td -DTD_ENABLE_JNI=ON .. && 
    cmake --build . --target install && 
    cd .. && 
    cd example/java && 
    rm -rf build && 
    mkdir build && 
    cd build && 
    cmake -DCMAKE_BUILD_TYPE=Release -DJAVA_HOME=/usr/lib/jvm/java-1.8-openjdk/ -DCMAKE_INSTALL_PREFIX:PATH=/usr/local -DTd_DIR:PATH=$(readlink -f ../td/lib/cmake/Td) .. && 
    cmake --build . --target install && 
    cd ../../.. && 
    cd .. && 
    ls -l /usr/local

CMD ["/bin/sh"]

But result remained the same.
Then I specified the path to my built tdjni when starting jar inside new container:
java -Djava.library.path=/usr/local:/usr/local/bin -jar /d/work/otus/repos/watchbot/build/libs/watchbot-1.0-SNAPSHOT-all.jar
Library was found this time:

Why it requires org/drinkless/tdlib/Client while I’m using TDLight, which should contain TDLib API? I decided to "show him" where the TDLib compiled Java classes are located (they were created by build commands):
java -Djava.library.path=/usr/local:/usr/local/bin -cp /d/work/otus/repos/watchbot/build/libs/watchbot-1.0-SNAPSHOT-all.jar:/usr/local/bin name.nepavel.otus.watchbot.MainKt
and got:

        at name.nepavel.otus.watchbot.MainKt.main(Main.kt)

Now it looks like TDLight expects another version of TDLib native (as far as I can see). What am I doing wrong? How to make it work?

I have tried different base images, different JAVA_HOME, different JDK from 11 to 17,
different TDLight dependencies in build.gradle, but nothing changed. I suppose that the mistake is small and stupid, but I can’t find it by myself.

    The first stacktrace says that you don’t have libc++ installed: libc++.so.1: No such file or directory

    You are using the following classifiers that require libc++: linux_amd64_ssl1 and linux_amd64_ssl3.

    If you don’t have libc++ and you don’t want to install it, you should choose the following classifiers instead: linux_amd64_gcc_ssl1 and linux_amd64_gcc_ssl3

    Faced the same problem. The reason may be that your openjdk:17-alpine image does not have the required openssl version. Try updating openssl like here. It helped me and this guy.

    FROM  openjdk:17-jdk-slim-bullseye
#Perl is required to install openssl
RUN apt-get update 
    && apt-get install -y ca-certificates wget bash 
    && apt-get -qy install perl

#Remove current openssl
RUN apt-get -y remove openssl

#This is required to run “tar” command
RUN apt-get -qy install gcc

RUN apt-get -q update && apt-get -qy install wget make && 
    wget https://www.openssl.org/source/openssl-1.1.1g.tar.gz &&  
    tar -zxf openssl-1.1.1g.tar.gz && cd openssl-1.1.1g && 
    ./config && 
    make install

WORKDIR /app

ADD build/libs/*.jar /app/libs/
ADD build/resources/* /app/resources/

ENTRYPOINT ["sh", "-c", "java ${JAVA_OPTS} -jar /app/libs/example.jar"]
