Error running Grails 3 application on CMD - grails

I am new to Grails and never made any project on it. I followed some tutorials and downloaded both Grails and JDK and set my environment variables exactly as specified, but when I tried to run the application, I got this error and my application is not running:
Error initializing classpath: could not determine java version from '10.0.2'
I just used CMD and none of the IDE is used, please help me solve this problem.

First check classpath of both for Java & Grails by running these command java -version & grails -version
If you found problem in classpath then solve by this way http://grails.asia/grails-tutorial-for-beginners-setup-your-windows-development-environment/
Although its better to use Java 8, not Java 10

OfBiz Installation Failure

Apache OfBiz is not installing correctly, and fails to compile in the command prompt.
After creating the system variable JAVA_HOME to C:\Program Files\Java\jdk1.8.0_40, and editing "Path" to be C:\Program Files (x86)\Java\jre7\bin;C:\apache-ant-1.9.4\bin, I downloaded OfBiz 13.07.01 to my C:\ folder and unzipped it there. In the command prompt, I typed the following:
C:\Users\CalS>cd C:\apache-ofbiz-13.07.01
C:\apache-ofbiz-13.07.01>ant load-seed
Then, after about 50 seconds, I get this:
BUILD FAILED
C:\apache-ofbiz-13.07.01\build.xml:229: the following error occurred while executing this line:
C:\apache-ofbiz-13.07.01\build.xml:248: the following error occurred while executing this line:
C:\apache-ofbiz-13.07.01\build.xml:39: the following error occurred while executing this line:
C:\apache-ofbiz-13.07.01\build.xml:91: compile failed; see the compiler error output for details.
Please note it has been years since I dealt with DOS, so I do not know how to access the error output.
This is after I get a few dozen errors like:
[javac16] class file for org.ofbiz.widget.ContentWorkerInterfaice not found
and
[javac16] warning: [options] bootstrap class path not set in conjunctions with -source 1.6
Under 'classes'.
Misc. I have tried 'ant run-install' and 'load-demo' commands without avail. I've followed step-by-step tutorials, but very likely missed something. Please let me know what I can do to fix this and run this program successfully. Thanks!
Please have a look at the following Apache Jira Tickets for OFBiz where your problem is addressed and was fixed, so that OFBiz could be build with java 1.8.
The build errors occur due to missing fileset entries in the build.xml for some applications (party, workeffort, product, order, ebay, and pos), see: OFBIZ-5835
A fix is available in related ticket: OFBIZ-6079
There was another bug in the current release branches (checked 14.12.01, 12.04.06, 13.07.02) that I fixed last week. The fix is already committed to the branches.
See: OFBIZ-6252
You have to compile/run with the same Java version.
Seems you have some inconsistencies: JAVA_HOME ist 1.8, Path is set to jre 7 and the warning states it is using an 1.6 compiler.
With the 13.07. Release, using Java 1.7 or 1.8 is recommended and supported.
Alright, so it looks like Apache OFBiz and Java JDK 1.8.XX don't get along. I found help on another forum that confirmed the discrepancy in compatibility between OFBiz 13.07.01/Apache ant 1.9.4 and JDK 1.8.XX. This will cause the compiling of the Apache Ant to fail (which seems to run off of JDK 1.6).
I remedied the problem by downloading the archived JDK 1.7.0_67 from Oracle, re-mapping the System Variables accordingly, and re-initializing the Command Prompt.
It works now! Thank you all for your contributions.
Though solved, let me add something important. JDK version is not always an issue in such errors. Ofbiz v13.X.X works well on JDK 1.7 and above. The error shown is a peculiar issue with Ofbiz v13.07.01 dist.
As Martin pointed out, one need to add widget jars in the classpath of order, party, product & workeffort. Add the below line
<fileset dir="../../framework/widget/build/lib" includes="*.jar"/>
in build.xml of order, party, product & workeffort under applications directory.

ggts null pointer "Retrieving available scripts"

I installed a fresh copy of GGTS on a fresh copy of windows 8 with JDK 1.7 installed.
I tried to get it to compile my existing project which was based on 2.3.6 and it failed miserably as GGTS comes with grails 2.4.2.
I know serveral people who had problems with 2.4.x so decided to stick with 2.3.
So I downloaded 2.3.11 (latest 2.3) and created a GRAILS_HOME pointing to 2.3.11 dir, and JAVA_HOME pointing to the root of the JDK.
On command line, I can now type grails - version and get back 2.3.11.
I restarted GGTS, and deleted the project and createde it again, adding 2.3.11 as a new Grails version, and set the project to use that.
It fails to compile, saying version is wrong. Fair enough. But when I try to launch the command line from GGTS using the gree circular button at the top which looks like 3 cups, it says:
Retrieving available scripts
Retrieving available scripts
An internal error occurred during: "Retrieving available scripts".
java.lang.NullPointerException
Any ideas?
In my case the problem was, that I had moved grails to a different folder. I just had to change the location of grails in the settings. Hope that helps somebody.
check all grails-project's 'app.grails.version' in application.properties, then open window - preferences - groovy -grails, make sure that all VERSIONs were defined ( I use sts, maybe a little difference ).
alternatively
update all application.properties set app.grails.version=2.3.11 ( the version your ggts defined )
Check if your environment variable of GRAILS_HOME is set to the right version of Grails.
I ran into this same issue, and the problem was caused by the Grails installation it was trying to use. It wanted to use the default version that comes with GGTS rather than the one I installed myself.
To fix, go to Window > Preferences > Groovy > Grails, then "Edit" the Grails installation it shows. I had to switch mine from C:\ggts-bundle\grails-2.4.4\ to C:\grails-2.4.2\.

Grails org.slf4j.spi.LocationAwareLogger.log not found

I'm using Grails 2.3.8
I've created a default app using
grails create-app testapp
When I run:
grails runApp
I get the following issue:

I tried running:
grails dependency-report
but I get the same issue.
java -version
gives:
java version "1.7.0_17"
Java(TM) SE Runtime Environment (build 1.7.0_17-b02)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
Not sure if this is your problem, but I vaguely recall there being some problems with Groovy and the earlier versions of Java 7. I'd recommend moving to the most recent. I have no problems with 2.3.8 and jdk1.7.0_55 (most recent at time of writing).
Have you looked for conflicting versions of slf4j? Try running Grails dependency-report.
There are a few other SO questions that indicate this to be a cause of issue. Eg: java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log
sl4j error in weblogic when deploying grails application war
One thing that can help in debugging situations like this is doing:
export JAVA_OPTS="-verbose"
You can then see which slf4j JAR is being loaded by the JVM, but yes there is undoutably some conflicing slf4j JAR on your classpath
There was an instance of slf4j in:
/Library/Java/Extensions/
Moving that out seems to have fixed the problem.

Can't get Grails application to run on Windows 7

I'm having trouble running Grails on my PC (running Windows 7).
It's been a couple of years since I last worked with Grails, and I have a new computer. So I downloaded Grails and NetBeans and followed the instructions. (Grails: version 2.3.7, NetBeans: version 7.4.)
Everything seems to be working. Both the Java JDK and Grails work - I can run "grails" from the command prompt. And it was easy to activate the support for Grails in NetBeans.
I created a very simple "Hello world" application. It compiles fine - and I can run "grails war" to create a War file. But I can't get it to run on my PC. I get the same error using "Run" in NetBeans and when running "grails run-app" at the command prompt:
|Running Grails application
Error opening zip file or JAR manifest missing : C:\Program%20Files\Grails

And the program won't start. The jar in question isn't missing, so I can't see what's wrong. Any ideas? I'd be more than grateful for some help! :-)

Move your copy of grails to C:\ and try again.
There is a known problem with location with space symbol. You can see it in stacktrace:

Grails: Native2ascii error when I add a new property to message.properties

I get a strange error when I add a new property to message.properties file in my grails application during runtime. When I restart the application via the command line, or restart STS, this error disappears. I am on version 2.0.1 and until a week ago, I was able to add new properties to message.properties file during runtime. Here is the stacktrace of the error
| Error 2012-06-18 16:54:58,702 [Thread-38] ERROR plugins.AbstractGrailsPluginManager - Plugin [i18n:2.0.1] could not reload changes to file [/home/project/grails-app/i18n/messages.properties]: Error starting Sun's native2ascii:
Message: Error starting Sun's native2ascii:
Any ideas?
cd to jdk path
cp lib/tools.jar jre/lib/ext/tools.jar
It solves the issue.
Note: to get correct jdk path,
check GGTS --> Windows --> Preferences --> Java --> Installed JREs --> JREs Home Path
You should be using JDK rather than JRE.
Also, if you don't need the native2ascii (which you probably don't), in BuildConfig.groovy use: grails.enable.native2ascii = false
Very frustrating bug.
After I executed all the steps suggested above in this thread, grails app was STILL not seeing tools.jar...
GRRR!
For anyone experiencing this problem in GGTS when pointing to the 1.7 jdk (when setting the jre) persisting afterwards, you MUST do the following:
Pick the correct jdk (1.7) in the "JRE Definition" panel within "Installed JRE's" in the GGTS Preferences panels.
Watch the jars from that jdk populate in the JRE definition window panel at the bottom "JRE System Libraries".
Check for tools.jar (mine DID NOT show up as recognized within the jdk lib or, after i tried 'zawmn83's post above) in /lib/ext.
If tools.jar does not show up as recognized in the jdk, click the "Add External JARs..." button, find it, add it.
That completely solve my problem - THANK GOD!!!!
p.s. i also had to set my JAVA_HOME to my 1.7 jdk correctly, in my .bash_profile but, that's already called out here as part of the solution.
Thanks everyone for contributing on this one - this bug has been causing me brain damage whilst tinkering with it today, and the above suggestions got me 99% of the way there!
I had a similar problem, in the end I
Removed the Debug Config for the Project
Deleted the project (but NOT the files)
Removed the .settings directory
Removed the .classpath and .project files from the project
Created a New General Project with the same name in the workspace
Recreated the Debug -> Run as Run-App
Hope this helps
This happened to me when I installed java 8 in parallel with java 7 on Ubuntu but didn't properly configure it with update-alternatives. Specifically, JAVA_HOME was not set properly.
I had a similar error when compiling Grails 2 from the command line under linux.
Error packaging application: Error occurred processing message bundles: Error starting Sun's native2ascii:
...
Caused by: : Error starting Sun's native2ascii:
...
Caused by: java.lang.ClassNotFoundException: sun.tools.native2ascii.Main`
I solved it by setting JAVA_HOME to JDK as mentioned above, something like
JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.161.x86_64
and not:
JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64
also include $JAVA_HOME/bin in the PATH variable
On linux, running grails war command, it solves the issue
cp /usr/lib/jvm/java-1.8.0-openjdk/lib/tools.jar /usr/lib/jvm/java-1.8.0-openjdk/jre/lib/ext/
