[Error] gradle build Heap Memory Issue - Caused by: java.lang.OutOfMemoryError: Java heap space / error message: java.lang.OutOfMemoryError: Java heap space

1. 에러 내용

회사에서 기능 추가를 하고 평소와 같이 빌드를 하려는데 에러가 발생했다.

처음에는 뭔가 싶었는데 우려했던 부분 때문에 힙 메모리 부족으로 인한 이슈가 발생했다.

 

에러 내용은 아래와같다.

2. 문제 해결

이 문제를 해결하기 위해서 몇 가지 검색을 통해 gradle 부분에 설정을 추가해주면 된다는 실마리를 찾았다.

해당 문제를 해결하기 위해서 Kotlin 공식 사이트를 참고했다.

https://kotlinlang.org/docs/gradle-compilation-and-caches.html#the-kotlin-daemon-and-how-to-use-it-with-gradle

Compilation and caches in the Kotlin Gradle plugin | Kotlin

 

설정을 추가해주는 방법은 공식 사이트를 참고하면 되는데 필자는 build.gradle.kts에 설정을 추가해줬다.

아래 내용은 build.gralde.kts의 일부분을 가져온 것이면 추가한 설정은 kotlinDaemonJvmArguments.set(listOf("-Xmx1500m")) 이 부분이다.

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        kotlinDaemonJvmArguments.set(listOf("-Xmx1500m"))
        jvmTarget = "17"
    }
}

 

위 설정을 추가해주니 힙 메모리 부족으로 인한 bulid Fail은 해결이 되었고, build도 성공적으로 마쳐서 배포를 할 수 있었다.
