Hey there! As described above I encountered problems while deploying my spring boot application via GitHub.
The error from build logs:
Build failed with an exception.
- What went wrong: Could not determine the dependencies of task ':compileKotlin'. > Cannot find a Java installation on your machine (Linux 6.1.0-37-cloud-amd64 amd64) matching: {languageVersion=17, vendor=any vendor, implementation=vendor-specific, nativeImageCapable=false}. Toolchain download repositories have not been configured.
current build.gradle.kts file:
plugins {
kotlin("jvm") version "1.9.25"
kotlin("plugin.spring") version "1.9.25"
kotlin("plugin.jpa") version "2.0.21"
id("org.springframework.boot") version "3.5.7"
id("io.spring.dependency-management") version "1.1.7"
}
group = "eu.project"
version = "0.0.1-SNAPSHOT"
description = "Demo project for Spring Boot"
java {
toolchain {
languageVersion.set(JavaLanguageVersion.of(17))
}
}
repositories {
mavenCentral()
}
dependencies {...}
kotlin {
compilerOptions {
freeCompilerArgs.addAll("-Xjsr305=strict")
}
}
tasks.withType {
useJUnitPlatform()
}
tasks.withType {
options.release.set(17)
}

Are you using a Dockerfile? Railway has some guides on how to deploy a Spring Boot application

Had the same issue. It's because of Railpack not being able to see which java version you're using and it defaults to java 21.
I added a railpack.json file to the root of my project with this configuration where I tell Railpack to use java 17 instead of defaulting to java 21.
{ "$schema": "https://schema.railpack.com", "packages": { "java": "17" }, "deploy": { "startCommand": "java $JAVA_OPTS -Dserver.port=$PORT -jar $(ls -1 build/libs/*.jar | grep -v plain | head -n 1)" } }
