Unable to compile/run when mix a jmix Java application with kotlin classes

manfred · January 18, 2023, 10:16am

Hello all,
I started generating a fullstack Java application, and when I first used a kotlin class, the project stops compiling with following error:

Caused by: java.nio.file.NoSuchFileException: /daten/workspaces/jmix/demo/build/tmp/entitiesEnhancing/main/persistence

My platform is:
The jmix-version is 1.4.2 with Amazon coretto java 11.
The database I am using is a mysql.
I am using latest the intellij 2022.3.1 Ultimate Edition

I tracked down the problem to the point when I first used kotlin. After that, the compile failed.
I also observed that the entities are not listed during compile-Time, as if there were none.

You can easily reproduce it with

create new jmix project, full stack Java
configure database and generate model from database, import an entity
. compile and run-> OK

Here is the build.gradle from 1st, running version:


plugins {
    id 'io.jmix' version '1.4.2'
    id 'java'
}

apply plugin: 'org.springframework.boot'

jmix {
    bomVersion = '1.4.2'
}

group = 'com.company'
version = '0.0.1-SNAPSHOT'

repositories {
    mavenCentral()
    maven {
        url 'https://nexus.jmix.io/repository/public'
    }
}

dependencies {
    implementation 'io.jmix.core:jmix-core-starter'
    implementation 'io.jmix.data:jmix-eclipselink-starter'
    implementation 'io.jmix.ui:jmix-ui-starter'
    implementation 'io.jmix.ui:jmix-ui-data-starter'
    implementation 'io.jmix.ui:jmix-ui-themes-compiled'
    implementation 'io.jmix.ui:jmix-ui-widgets-compiled'
    implementation 'io.jmix.security:jmix-security-starter'
    implementation 'io.jmix.security:jmix-security-ui-starter'
    implementation 'io.jmix.security:jmix-security-data-starter'
    implementation 'io.jmix.localfs:jmix-localfs-starter'
    implementation 'io.jmix.datatools:jmix-datatools-starter'
    implementation 'io.jmix.datatools:jmix-datatools-ui-starter'

    implementation 'org.springframework.boot:spring-boot-starter-web'


    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    implementation 'mysql:mysql-connector-java'
}

test {
    useJUnitPlatform()
}

create a new kotlin class and configure kotlin for the project “as Kotlin Java with Gradle) module” run all imports for kotlin support
after that, compile will fail with the error above (I added the complete console output at the end)

Here is the build.gradle after configuring kotlin

buildscript {
    ext.kotlin_version = '1.8.0'
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
plugins {
    id 'io.jmix' version '1.4.2'
    id 'java'
}

apply plugin: 'org.springframework.boot'
apply plugin: 'kotlin'

jmix {
    bomVersion = '1.4.2'
}

group = 'com.company'
version = '0.0.1-SNAPSHOT'

repositories {
    mavenCentral()
    maven {
        url 'https://nexus.jmix.io/repository/public'
    }
}

dependencies {
    implementation 'io.jmix.core:jmix-core-starter'
    implementation 'io.jmix.data:jmix-eclipselink-starter'
    implementation 'io.jmix.ui:jmix-ui-starter'
    implementation 'io.jmix.ui:jmix-ui-data-starter'
    implementation 'io.jmix.ui:jmix-ui-themes-compiled'
    implementation 'io.jmix.ui:jmix-ui-widgets-compiled'
    implementation 'io.jmix.security:jmix-security-starter'
    implementation 'io.jmix.security:jmix-security-ui-starter'
    implementation 'io.jmix.security:jmix-security-data-starter'
    implementation 'io.jmix.localfs:jmix-localfs-starter'
    implementation 'io.jmix.datatools:jmix-datatools-starter'
    implementation 'io.jmix.datatools:jmix-datatools-ui-starter'

    implementation 'org.springframework.boot:spring-boot-starter-web'


    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    implementation 'mysql:mysql-connector-java'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}

test {
    useJUnitPlatform()
}
compileKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}
compileTestKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

The console output is

Hi,

There is an issue for the same problem. We’ll try to do something with it in the upcoming 1.5 release.

manfred · January 20, 2023, 8:05am

Hi,
thanks for the reply.
Then we have to wait until it’s fixed, if there is no workaround…

gorbunkov · January 20, 2023, 9:29am

I looked at the problem again and it seems that it is not the issue I thought initially.

Try doing the following:

Create a separate kotlin directory where all your kotlin sources will be
Convert main spring boot application class (the one with the @SpringBootApplication annotation) from java to kotlin (that seems to be the reason of the error). Make sure that the class ant its members have the open keyword.
If while running you have problems like spring cannot find the main class or similar, try renaming the main application class

Hi,
thanks for investigating.
I will check the workaround.

Hopefully you are still looking into fixing the main problem, since we are mainly implementing in java.

Manfred
