OutOfMemoryError when compiling my android app with gradle

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. Consult the following stack trace for details. java.lang.OutOfMemoryError: Java heap space     at com.sun.tools.javac.util.Position$LineMapImpl.build(Position.java:139)     at com.sun.tools.javac.util.Position.makeLineMap(Position.java:63)     at com.sun.tools.javadoc.DocCommentScanner.getLineMap(DocCommentScanner.java:438)     at com.sun.tools.javac.main.JavaCompiler.parse(JavaCompiler.java:512)     at com.sun.tools.javac.main.JavaCompiler.parse(JavaCompiler.java:550)     at com.sun.tools.javac.main.JavaCompiler.parseFiles(JavaCompiler.java:804)     at com.sun.tools.javac.main.JavaCompiler.compile(JavaCompiler.java:727)     at com.sun.tools.javac.main.Main.compile(Main.java:353)     at com.sun.tools.javac.api.JavacTaskImpl.call(JavacTaskImpl.java:115)     at org.gradle.api.internal.tasks.compile.jdk6.Jdk6JavaCompiler.execute(Jdk6JavaCompiler.java:40)     at org.gradle.api.internal.tasks.compile.jdk6.Jdk6JavaCompiler.execute(Jdk6JavaCompiler.java:33)     at org.gradle.api.internal.tasks.compile.NormalizingJavaCompiler.delegateAndHandleErrors(NormalizingJavaCompiler.java:95)     at org.gradle.api.internal.tasks.compile.NormalizingJavaCompiler.execute(NormalizingJavaCompiler.java:48)     at org.gradle.api.internal.tasks.compile.NormalizingJavaCompiler.execute(NormalizingJavaCompiler.java:34)     at org.gradle.api.internal.tasks.compile.DelegatingJavaCompiler.execute(DelegatingJavaCompiler.java:29)     at org.gradle.api.internal.tasks.compile.DelegatingJavaCompiler.execute(DelegatingJavaCompiler.java:20)     at org.gradle.api.internal.tasks.compile.IncrementalJavaCompilerSupport.execute(IncrementalJavaCompilerSupport.java:33)     at org.gradle.api.internal.tasks.compile.IncrementalJavaCompilerSupport.execute(IncrementalJavaCompilerSupport.java:24)     at org.gradle.api.tasks.compile.Compile.compile(Compile.java:68)     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)     at java.lang.reflect.Method.invoke(Method.java:597)     at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:90)     at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:233)     at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1047)     at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:877)     at org.gradle.api.internal.BeanDynamicObject$MetaClassAdapter.invokeMethod(BeanDynamicObject.java:216)     at org.gradle.api.internal.BeanDynamicObject.invokeMethod(BeanDynamicObject.java:122)     at org.gradle.api.internal.CompositeDynamicObject.invokeMethod(CompositeDynamicObject.java:147)     at org.gradle.api.tasks.compile.JavaCompile_Decorated.invokeMethod(Unknown Source)     at groovy.lang.GroovyObject$invokeMethod.call(Unknown Source) :myApp:compileDebug FAILED 

Any idea?

Answer 1

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

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.
