使用 gradle 编译我的 android 应用程序时出现 OutOfMemoryError

Question

I'm trying to build my app via gradle and I'm currently having this issue after running a ./gradlew build :

:myApp:compileDebug


The system is out of resources.

Any idea?

Answer 1

I think I fixed it. I got the solution from this post . ie:

replacing in gradlew:

GRADLE_OPTS="$GRADLE_OPTS \"-Xdock:name=$APP_NAME\" \"-Xdock:icon=$APP_HOME/media/gradle.icns\""

by

GRADLE_OPTS="$GRADLE_OPTS \"-Xdock:name=$APP_NAME\" \"-Xdock:icon=$APP_HOME/media/gradle.icns\" \"-Xmx1024m\" \"-Xms256m\" \"-XX:MaxPermSize=1024m\""

Answer 2

In my project there was a gradle.properties file with these lines:

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx10248m -XX:MaxPermSize=256m
# org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

I uncommented the last line, and that worked.

Answer 3

I also faced this problem on regular java project. Our test execution was extensive and used to run out of memory or permgen error.

So there are two soluton 1. Set the parameters and the run the build

export JAVA_OPTS="-Xmx1024M -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512M" 
export GRADLE_OPTS="-Dorg.gradle.daemon=true"

Second option simplifies the solution within in gradle file

test {
    jvmArgs "-XX:MaxPermSize=256m"
}

I recommend second option as its permanent fix.

Answer 4

dexOptions {

        incremental true

       //javaMaxHeapSize=1024M for 32bit Java,2048M for 64bit Java

       javaMaxHeapSize "1024M"

       //javaMaxHeapSize "2048M"
    }

Answer 5

FWIW，我通过将一个非常大的字符串硬编码到源文件中来重现“系统资源不足”错误（但使用另一个堆栈跟踪）。

Answer 6

Changing the JAVA_HOME folder to the 64-bit installation helped me too. Use 64-bit runner for IDEA after that.

Answer 7

我在构建服务器上遇到了同样的问题，一旦我将 JAVA_HOME 文件夹更改为 Java 的 64 位安装，错误就消失了。

Answer 8

For anyone using Gradle and Kotlin , nothing here worked and I spent hours looking for a solution. Here's what worked for me:

Add this anywhere to your build.gradle :

compileKotlin {
    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_1_8
        freeCompilerArgs = ['-Xjsr305=strict', '-XXLanguage:-NewInference']
    }
}

Answer 9

Ok I had this issue as well with a springboot project. I ended up by running the clean task and the problem was solved.
