Got Java JDK 7 running, but no dice for Gradle

[mphaney]

As the title says, I managed to extract the tar file from Oracle for JDK 7 and java seems to run alright, but Gradle (downloadable from Gradle.org) does not work. It is basically just a glorified wrapper and set of tools for Java. I know Java is sketchy on this build anyway (although hearing lots of positive things for the next build!) but I would love for Gradle to be tested along side it! Thanks.

Currently it just hangs (like Java 8 does). Here is the expected vs. current output:

Would it be possible for you to collect an strace when you run gradle? I can take a look and see if anything jumps out at me.

Absolutely! Apologies for the length, but here it is:

Update: I started fresh with build 14352 (completely removed Bash via the lxrun /uninstall etc, then reinstalled). Right out of the gate, I performed sudo apt-get install gradle. The install performed excellently and running gradle -v did indeed output the expected results:

`$ gradle -v

Gradle 1.4

Gradle build time: Monday, September 9, 2013 8:44:25 PM UTC
Groovy: 1.8.6
Ant: Apache Ant(TM) version 1.9.3 compiled on April 8 2014
Ivy: non official version
JVM: 1.7.0_101 (Oracle Corporation 24.95-b01)
OS: Linux 3.4.0+ amd64
`

HOWEVER, trying to actually use gradle in any meaningful way results in it simply hanging. Given that Java is already up to version 1.8.0_92 and Gradle is up to 2.13, I would much prefer to be able to simply install these products from their respective websites, alas, both hang without producing any output whatsoever :-/

[spsDrop]

Gradle hanging is one of my only blockers for using bash on Windows for work, which I would love to do. I get the same thing. Just no output when running gradle.

[mphaney]

Agreed. If they could get the current Oracle build of JDK and the current Gradle working, I could drop Cygwin, PowerShell and my SSH session to another actual Linux box. Is there any word on this, @benhillis?

[benhillis]

I'm not familiar with gradle, could somebody provide me with a repro that demonstrates some broken functionality that I can debug?

[mphaney]

@benhillis Here are the exact steps I followed (pre-supposes that "unzip" has been installed via apt-get).

Download the Oracle JDK and Gradle packages:
wget --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u5-b13/jdk-8u5-linux-x64.tar.gz
wget https://services.gradle.org/distributions/gradle-2.13-bin.zip

Then, for simplicity:
sudo su

Create the target folders:
mkdir /opt/jdk /opt/gradle

Extract each of the packages:
tar -zxf jdk-8u5-linux-x64.tar.gz -C /opt/jdk/
unzip gradle-2.13-bin.zip -d /opt/gradle/

If desired, verify the extractions:
ls /opt/jdk
ls /opt/gradle

Set defaults:
update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_05/bin/java 100
update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_05/bin/javac 100
update-alternatives --install /usr/bin/gradle gradle /opt/gradle/gradle-2.13/bin/gradle 100

Again, if desired, verify settings:
update-alternatives --display java
update-alternatives --display javac
update-alternatives --display gradle

Set environment variables:
JAVA_HOME=/opt/jdk/jdk1.8.0_05
GRADLE_HOME=/opt/gradle/gradle-2.13
export JAVA_HOME
export GRADLE_HOME

Verify Java works:
java -version

Should produce the following:

java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

Then attempt to run Gradle (simply hangs)
gradle -version

Expected output should be similar to this, obviously with different versions/OS/etc:

Update: I've never actually just let it sit and see what happens, but apparently when I do the following is produced:

On our dev build "gradle -version" is working for me. Are there some other things I can try?

[mphaney]

Oh, cool. I imagine that'll be making its way to us eventually then :-) Here is the most basic of tests:

Create a test folder:

mkdir gradle_test
cd gradle_test

Create a new file named build.gradle and add the following to it:

task compile << {
    println 'compiling source'
}

task compileTest(dependsOn: compile) << {
    println 'compiling unit tests'
}

task test(dependsOn: [compile, compileTest]) << {
    println 'running unit tests'
}

task dist(dependsOn: [compile, test]) << {
    println 'building the distribution'
}

Then simply run:
gradle dist test

Expected output should be similar to:

Starting a new Gradle Daemon for this build (subsequent builds will be faster).
:compile
compiling source
:compileTest
compiling unit tests
:test
running unit tests
:dist
building the distribution

BUILD SUCCESSFUL

[benhillis]

When I run the tests I'm seeing the same Internal Error you pasted above.

[mphaney]

Ah, well, I suppose progress in either direction is still progress. Thanks for looking into it :-) My job and my sanity thank you as well.

[spsDrop]

Is there any progress on this bug? Seems like there is a repo case now, right? This is still a big blocker for me.

[antillean]

There doesn't seem to be a fix yet, but as per issue 541 you can use export _JAVA_OPTIONS="-Xint" as a workaround.

[mphaney]

Hmm, that still doesn't seem to work for either java -version or gradle -version. I know the bigger problem has been mentioned (shared memory), but I figured it's worth mentioning that this workaround doesn't seem to help my case at all, unfortunately :-/

[leninalive]

Did you try to install openjdk-7/8/9-jre-zero instead of current JVM? Please try and update results. NB: for Zero JVM, it is not required to use export _JAVA_OPTIONS="-Xint" though please clean it out after apt-get install.

[leninalive]

I would also accourage you to update to Xenium/16.04 (find in issues a receipt to do so) and use OpenJDK 9 as it seems to be most reliable for WSL.

[mphaney]

Well, I did manage to get Xenial installed, but unfortunately openjdk-8-jre-zero still won't install. Simply hangs on this line Running hooks in /etc/ca-certificates/update.d.... Older versions are inadequate for our work and, basically, while this has been a fun exercise, I'll just need to wait until full support for the proper Oracle JDK and Gradle is worked out. Thank you for all the suggestions, though!

[therealkenc]

@mphaney - I couldn't install openjdk-8-jre[-zero] on Xenial either. It hangs in ca-certificates the same way as #541, #566 etc, because the hooks call java. What is interesting is that -Xint doesn't help. I also tried installing Eclipse on a lark and it also hangs even with -Xint. So while that workaround gets javac and Closure running, it doesn't seem to be a universal solution.

[leninalive]

@therealkenc - did you uninstall all other versions of Java before installing zero jvm?

[leninalive]

Also, probably if you are installing jre using sudo apt-get instead of sudo su, export _JAVA_OPTIONS="-Xint" and then apt-get you probably are not getting -Xint effective.

Try it this way:
sudo _JAVA_OPTIONS="-XInt" apt-get install openjdk-8-jre-zero

[DifferentSC]

@leninalive I followed your steps so I succeeded in installing openjdk-8-jre-zero. But when I type "java -version" it doesn't respond.

Any progress on this issue? It should be a blocking issue for many developers...

[KrzysztofKowalczyk]

As Java no longer hangs in insider built, this has been fixed and can be closed.
Now there are other problems with gradle, i.e. #851

To validate, having Java already installed:

• curl -s "https://get.sdkman.io" | bash // install a tool that can instal gradle, sbt etc.
• source "$HOME/.sdkman/bin/sdkman-init.sh"
• sdk install gradle // this will pick newest version
• gradle tasks

[chesterm8]

Gradle does appear to be running, however it cannot execute any tests (which I would consider core functionality) due to issues cloning processes. Details as per my comment here Issue 851

[jackchammons]

This issue is being tracked in #851
