I'm writing a Java program that runs from the command line and uses a library that I wrote to parse command line arguments. Since my library isn't on maven repository, I'm using flatDir in gradle to grab the jar from a directory local/ containing the jar file. Here is my build.gradle:
apply plugin: 'java-library'
repositories {
jcenter()
mavenCentral()
flatDir(dirs: 'local')
}
dependencies {
api 'org.apache.commons:commons-math3:3.6.1'
implementation 'com.google.guava:guava:21.0'
testImplementation 'junit:junit:4.12'
// https://mvnrepository.com/artifact/javax.mail/mail
compile group: 'javax.mail', name: 'mail', version: '1.4.1'
// https://mvnrepository.com/artifact/org.mongodb/mongodb-driver
compile group: 'org.mongodb', name: 'mongodb-driver', version: '3.4.2'
// https://mvnrepository.com/artifact/org.jsoup/jsoup
compile group: 'org.jsoup', name: 'jsoup', version: '1.7.2'
// https://mvnrepository.com/artifact/log4j/log4j
compile group: 'log4j', name: 'log4j', version: '1.2.12'
// not in maven repository
compile 'JModule:JModule:1.3.1'
}
task copyToLib(type: Copy) {
from configurations.compile
into 'dependencies'
}
build.dependsOn(copyToLib)
My code runs fine in the eclipse IDE, and runs fine from the command line when I comment out all the references to JModule (my library) and run it with all the other libraries I'm using. However, when I run it with JModule as a dependency, it produces the following error:
Error: A JNI error has occurred, please check your installation and try again

I've already tried removing references to the class com.JModule.commandLogic but this only produces the same error with other JModule classes. Just to be clear, I'm not yet exporting to a jar - I'm just running the main class from the command line using the "java" command. The jar is also in the eclipse folder "project and external dependencies" so I'm assuming this means it's in my classpath, since the other jars in there run fine in my program.
Any help would be appreciated, thanks

I have clean installed the latest version on IntelliJ and Gradle, ensuring Gradle is correctly set up in my Windows environment (I can run Gradle and build my project successfully through the command line in Windows and IntelliJ).
My issue arrises when I try to get IntelliJ to update the project when I make changes to my build.gradle file (see below). I get the following error and I cannot figure out what's gone wrong. This is a fresh project and fresh install of everything.

Trying to build a java application with gradle and deploy it to a heroku server. I have some issues on java -jar build/libs/MyApp-0.0.1.jar as it returns the following:
Exception in thread "main" java.lang.NoClassDefFoundError:
io/javalin/Javalin at products.ProductAPI.main(ProductAPI.java:7)
Caused by: java.lang.ClassNotFoundException: io.javalin.Javalin at

java.lang.ClassLoader.loadClass(ClassLoader.java:424) at
sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338) at
java.lang.ClassLoader.loadClass(ClassLoader.java:357)
To run your app without any NoClassDefFoundError, you should have your dependencies in the runtime class path. Creating a fat jar is the simplest solution. Change your jar section like below;
jar {
manifest {
attributes(
'Class-Path': configurations.compile.files.collect {"$it.name"}.join(' '),
'Main-Class': 'products.ProductAPI')}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
}
run gradle build command and jar with dependencies will be created.
Other way is to add jars to runtime class path are; with java -cp flag. (Also If your application has already a classpath folder configured, copying dependencies in this folder will add them to the classpath)
I'm new to Java projects and gradle. I'm trying to use Google's GSON to parse a JSON string.

}
test {
systemProperties 'property': 'value'
}
uploadArchives {
repositories {
flatDir {

}
}
}
I'm doing everything from the command line.
I've got my files saved under my-project-name/src/main/java/
Any help is much appreciated! I am stuck.
If you want to run single java file from command line, you need to provide gson jar as classpath using -cp jar_location in your command.
If you want to run build jar:
change dependencies from compile to runtime in your configuration.
dependencies {
runtime group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.8.6'
runtime group: 'commons-collections', name: 'commons-collections', version: '3.2.2'
runtime group: 'com.google.code.gson', name: 'gson', version: '2.8.0'
testCompile group: 'junit', name: 'junit', version: '4.+'
}
Change your jar config like following:
jar {
manifest {
attributes(
'Implementation-Title': 'gscc-groupme-logs',
'Implementation-Version': version
'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
'Main-Class': 'GetGroupMeMessages'
)
}
}
Then after creating the jar run it using java -jar jarname command.
After updating intelij i cannot run anymore testng.xml.
If i run my tests as a separate Class it works fine and runs. But if i run it as a suite Testng.xml i got error.
