log4j JsonTemplateLayout doesn't work when jar file built by shadowJar

I use shadowJar I use log4j2 and I need to log everything in json format. But once I add 'org.apache.logging.log4j:log4j-layout-template-json:2.17.1' into build.gradle file I'm getting this errors:

ERROR StatusLogger Unrecognized format specifier [d]
ERROR StatusLogger Unrecognized conversion specifier [d] starting at position 16 in conversion pattern.
ERROR StatusLogger Unrecognized format specifier [thread]
ERROR StatusLogger Unrecognized conversion specifier [thread] starting at position 25 in conversion pattern.
ERROR StatusLogger Unrecognized format specifier [level]
ERROR StatusLogger Unrecognized conversion specifier [level] starting at position 35 in conversion pattern.
ERROR StatusLogger Unrecognized format specifier [logger]
ERROR StatusLogger Unrecognized conversion specifier [logger] starting at position 47 in conversion pattern.

if I remove log4j-layout-template-json dependency usual logging become working, but I need logging in json format using JsonTemplateLayout.

here is my build.gradle file:

apply plugin: 'java'
apply plugin: "com.github.johnrengelman.shadow"


shadowJar {
    zip64 = true

}

dependencies {

    compileOnly 'org.projectlombok:lombok:1.18.22'
    annotationProcessor 'org.projectlombok:lombok:1.18.22'
    implementation 'org.apache.logging.log4j:log4j-api:2.17.1'
    implementation 'org.apache.logging.log4j:log4j-core:2.17.1'
    implementation 'org.apache.logging.log4j:log4j-layout-template-json:2.17.1'
    implementation 'org.apache.logging.log4j:log4j-slf4j-impl:2.17.1'
    testImplementation 'org.testng:testng:7.4.0'
}


tasks.named('test') {
    // Use TestNG for unit tests.
    useTestNG()
}

I also use gradle shadowJar plugin to build fat jar. Because I'm need to run my jar file this way: java -cp example-0.0.1-all.jar org.example.Main

Answering my question this is what worked for me:

import com.github.jengelman.gradle.plugins.shadow.transformers.Log4j2PluginsCacheFileTransformer

shadowJar{
    transform(Log4j2PluginsCacheFileTransformer)
}
