Error releasing lock on artifact cache: java.io.IOException: Bad file descriptor

lystochok · January 6, 2012, 8:49pm

After upgrade from 0.9.2 to 1.0-milestone-6 or 1.0-milestone-7 All that I get from gradle clean build is list of “Bad file descriptor” errors kind of:

Error releasing lock on artifact cache (/Users/mike/.gradle/caches/artifacts-7): java.io.IOException: Bad file descriptor

I tried to removing build and caches directory, but nothing helps. Any hint how to cure this?

The build.gradle is as simple as:

apply plugin: ‘java’

repositories {

mavenCentral() }

error is reproducible even with just: gradle clean

Error releasing lock on no_buildscript class cache for build file ‘/Users/…/build.gradle’ (/Users/…/.gradle/caches/1.0-milestone-7/scripts/build_5b4bcjsm6obmf8t02fk6ks22vv/ProjectScript/no_buildscript): java.io.IOException: Bad file descriptor

gradle -version:

Gradle 1.0-milestone-7 Gradle build time: Thursday, January 5, 2012 10:24:43 AM UTC Groovy: 1.8.4 Ant: Apache Ant™ version 1.8.2 compiled on December 20 2010 Ivy: 2.2.0 JVM: 1.6.0_03-p3 (Sun Microsystems Inc. 1.6.0_03-p3-landonf_19_aug_2008_14_55-b00) OS: Darwin 9.8.0 i386

Could it be that my JVM (http://landonf.bikemonkey.org/static/soylatte/) somehow become compatible with recent 1.0 milestones?

I do find some issue with cache locking e.g. GRADLE-1801 but they don’t exactly match my problem I believe (and they are fixed in 1.0-m7).

There is also stack trace that I get only for some runs (inconsistently):

BUILD FAILED

Do you have a stack trace for the ‘error releasing lock’ problem? You can run gradle with -s to get the stack trace.

Also, could you try your build with the Apple JVM, or a recent openjdk 7 build?

lystochok · January 9, 2012, 8:18am

Unfortunately openjdk 7 requires 64 bit system, I have 32 only, so I can run Java 6 only using soylatte JVM.

I tried running gradle with Apple JVM v5 and it indeed worked. So as long as gradle works with Java 5 it should be good workaround. Although I need specifically set that gradle have to use Apple JVM v5 instead of Java 6 default one.

So currently before running gradle I just need:

export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Home

Please let me know if you know other way to make it default choice for gradle. As I install gradle from port

sudo port install gradle-devel I can of course edit directly the script

/opt/local/share/java/gradle/bin/gradle and set JAVA_HOME in it.

It would be nice to have some .gradlerc to set it there externally.

Thanks for help/pointers anyway. I haven’t thought it could be jvm-gradle compatibility issue. Not sure if you need to fix this regression and use of soylatte jvm is probably very rare but there is no other Java 6 choice on 32 bit Intel macs for now. And good that there is workaround to use Apple JVM v5.
