Expo Eas: fail exporting - react-native

Question

I have resumed a project that I started a few months ago, an app that I am building in react native. The problem is that when going to compile it told me that I had to update to eas. I have updated and now when trying to do a build it tells me:
[stderr] FAILURE: Build completed with 2 failures.
[stderr] 1: Task failed with an exception.

my code in build.gradle is the following (I've already changed the maven call to maven-publish but it's still the same):
apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'java-library'
apply plugin: 'maven-publish'
group = 'org.unimodules'
version = '6.7.1'
buildscript {
// Simple helper that allows the root project to override versions declared by this library.
ext.safeExtGet = { prop, fallback ->
rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
}
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:6.7.1'
classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${safeExtGet('kotlinVersion', '1.4.21')}")
}
}
//Upload android library to maven with javadoc and android sources
configurations {
deployerJars
}
//Creating sources with comments
task androidSourcesJar(type: Jar) {
classifier = 'sources'
from android.sourceSets.main.java.srcDirs
}
//Put the androidSources and javadoc to the artifacts
artifacts {
archives androidSourcesJar
}
uploadArchives {
repositories {
mavenDeployer {
configuration = configurations.deployerJars
repository(url: mavenLocal().url)
}
}
}

Do you know how I can solve it? Thanks.
