Generator fails to run NoClassDefFoundError: org/greenrobot/greendao/generator/Schema #619

baylonedward · 2017-03-24T07:32:16Z

This error just suddenly occur when I am about to update my database using green dao.
It seems it can find Schema class from greendao lib. I am using Android Studio 2.3.

greenrobot-team · 2017-03-27T06:12:43Z

Do you have a stacktrace or an example project? Otherwise it is a little hard to guess what this issue is caused by.

Typically this might be caused by missing configuration for ProGuard or multidex.

greenrobot-team · 2017-03-28T05:32:58Z

Now I see: looks like greenDAO generator is missing from your classpath. Make sure that you have a dependency on the generator (like compile 'org.greenrobot:greendao-generator:2.2.0') in the Java module build file where ProductionAppDao is a part of. -ut

baylonedward · 2017-03-29T01:08:18Z

apply plugin: 'java'

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'org.greenrobot:greendao-generator:3.2.0'
}

sourceCompatibility = "1.7"
targetCompatibility = "1.7"

//I think not I have all along in the gradle build dependencies.

baylonedward · 2017-03-29T01:16:59Z

nothing is change in the code,
I just want to rerun it.
but after upgrading to new Android Studio it can't find the Schema class.
This might be incompatibility with the new version of Android Studio 2.3.
You might want to try it.

workofgao · 2017-03-29T06:23:33Z

Hello! I also metting this trouble. Find a long time,lastly I try add ' MultiDex.install(this); ' at myapplication! After that my app is well running! Hope to help you ! Ignore my terrible English

baylonedward · 2017-03-29T07:23:12Z

hi,
where should I put multidex.install(this)?

workofgao · 2017-03-29T07:28:55Z

hi ! in your application.java ‘s oncreate() ！ I sended an email to you for example picture

baylonedward · 2017-03-30T06:07:24Z

Hi did not receive any email.
Is there any solution to this problem?
dao generator class is a java application so MultiDex won't work i think.

greenrobot-team · 2017-04-03T06:23:42Z

Oh, I just see that this might be a known issue: try to run code generation using Gradle.

Add the class with the main() method to your build.gradle file:

apply plugin: 'application'
mainClassName = "com.pmrpallet.ProductionAppDao"

Then in Android Studio execute the Gradle run task:

Update: I added this to the documentation.
-ut

baylonedward · 2017-04-03T07:16:30Z

Hi,

I did not make my own application class for my dao generator.
I simply create a generator class so no application/run directory on my Gradle view.

greenrobot-team · 2017-04-03T07:38:03Z

@baylonedward As said, you need to apply the application plugin and configure your generator class. See my comment above. -ut

baylonedward · 2017-04-04T00:51:16Z

Oh i see.
Thanks.
Was able to generate dao now.
But I want to know the reason why suddenly it won't work the normal way?
Is there any fix coming for this?

FriedrichMaximilian · 2017-04-04T08:52:34Z

hi,
i had the same issue, after upgrading to Android Studio 2.3. suddenly greendao doesn't work. I read all the comments above, but can't follow your instructions.
In which build.gradle file should i add :
apply plugin: 'application'
mainClassName = "com.pmrpallet.ProductionAppDao"

I have three of them, the root build.gradle , the app build.gradle and the greendao build.gradle.

In my app build.gradle file i apply the plugin: 'com.android.application' , so adding apply plugin: 'application' is not compatible.

I want to use the old greendao generation file i created with Version 2.0.0. Now i upgraded greendao to version 3.2.0. ( i changed all imports in the generation file). Normaly this should work or not?

Please give me some hints to get it work.

Best regards.

greenrobot-team · 2017-04-04T08:55:59Z

@Diatore You should add it to the build.gradle file where you use the generator.

To learn how to update to greenDAO 3 have a look at the docs.

@baylonedward This is an Android Studio/IntelliJ IDEA issue. I am not sure there is anything we can do about it from our side.

@jeffreyliu8 @mrrobot97 Using Android Studio 3 RC1 and JDK Build 1.8.0_141-b15 the run task continues to work fine using greenDAO 3.2.2.

@mrrobot97 I have not tested with 1.3.0. But as @jeffreyliu8 has the same issue for a different greenDAO version and it works fine on my machine I assume this is a configuration problem on your machines.

willemevenwel · 2017-10-19T23:18:03Z

Thanks to the above answers, I experienced the same issues moving to AS 3 preview.

What solved it for me was moving the execution of the generator to a gradle task, and adding the application plugin to my generator module’s build.gradle. As explained by the greendao users. Thanks. I would really like to know why this works tho.

Additionally before I got it to work, I experienced the issue “blablabla finished with non-zero exit value 1”, but this was because of a typo in my package and generator class string value for mainClassName value.

Additionally I am using GreenDao version 2.1. (de.greenrobot:greendao-generator:2.1.0)

mrrobot97 · 2017-11-01T02:13:22Z

@greenrobot-team Finally I figured out why would I get this error:
Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1.

I'm using greendaogenerator in a seperate module and the out-dir is in another module named "data". I used to used
new DaoGenerator().generateAll(schema, "data/src/main/java-gen");
to genetate tables.
While now I must use
new DaoGenerator().generateAll(schema, "../data/src/main/java-gen");
It seems that the relative path of the outDir differed.

in build.gradle file.
apply plugin: 'application'

and then sync the gradle

and also need to update the generate output directory, like:
new DaoGenerator().generateAll(schema, "../app/src/main/dao");

@VinsonCai thanks for the quick response. I tried as per your suggestion but I'm getting some other issue. any idea on this?

iskugor · 2017-11-15T10:19:44Z

Hello.

I tried suggested workaround, but it didn't work for me.

I figured out the issue happens because of new gradle 3.0 version, if you download gradle version 2.3 it works fine (so you can still use new Android Studio).

I'm using SQLCipher (3.5.7) and GreenDAO encryption generator (org.greenrobot:greendao-generator-encryption:2.2.0) on MacOS.

Cheers

In case this helps someone: I managed to fix the issue by executing the Gradle 'run' command directly from the command-line as described in this SO answer:

glenaries03 · 2017-12-06T13:22:20Z

Got it working!
Like the answer above.
@abelsee I just ran the greendaoGenerator from Gradle projects.
It's in the extreme right if you are using Android Studio.

AbelBeneberus · 2017-12-06T18:03:18Z

@blueboxsolution tnx alot it worked ......

Roby8023 · 2018-01-25T08:47:26Z

@xTheITx X thx, it spent me a lot time until find your answer.

silentsudo · 2018-02-27T12:24:54Z

@greenrobot-team has the perfect answer and its there in documentation,
Solution worked for me is:

apply plugin: 'application'
mainClassName = "com.example.Generator"

In Java code replace
app/src/main/java -> ../app/src/main/java (path of generated files)

Once this is done, follow steps below:

Got to Edit configuration
Create New Gradle Configuration
Select gradle project
add run as task
Press play, all files should be generated successfully now.

naitbrahim · 2018-04-30T17:44:02Z

For me I have to delete apply 'java' from my daogenerator module and put these lines instead :

apply plugin: 'application'
mainClassName = "com.example.GreenGenerator"
sourceCompatibility = 1.8

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'org.greenrobot:greendao-generator:2.2.0'
}

hpeiyan · 2018-09-28T09:49:02Z

Android studio3.0.1, GreenDao3.2.3 or 2.3.3; all above answers are unused. It had spent me one afternoon.....

hpeiyan · 2018-09-28T10:13:21Z

Thank God. I have upgrade Android Studio from 3.0.1 to 3.2.0, and it's correct.
