Maven Out of Memory Build Failure

Question

As of today, my maven compile fails.

[INFO] [ERROR] Unexpected
[INFO] java.lang.OutOfMemoryError: Java heap space
[INFO]  at java.util.Arrays.copyOfRange(Arr         


        

Answer 1

I got same problem when compiling Druid.io, increasing the MaxDirectMemorySize finally worked.

export MAVEN_OPTS="-Xms8g -Xmx8g -XX:MaxDirectMemorySize=4096m"

Answer 2

While building the project on Unix/Linux platform, set Maven options syntax as below. Notice that single qoutation signs, not double qoutation.

export MAVEN_OPTS='-Xmx512m -XX:MaxPermSize=128m'

Answer 3

_JAVA_OPTIONS="-Xmx3G" mvn clean install

Answer 4

Using .mvn/jvm.config worked for me plus has the added benefit of being linked with the project.

Answer 5

Increasing the memory size in the environment variable 'MAVEN_OPTS' will help resolve this issue. For me, increasing from -Xmx756M to -Xmx1024M worked.

Answer 6

I got same problem trying to compile "clean install" using a Lowend 512Mb ram VPS and good CPU. Run OutOfMemory and killed script repeatly.

I used export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=350m" and worked.

Still getting some other compiling failure because is the first time i need Maven, but OutOfMemory problem has gone.
