Cannot Load Java Resources in Spark from Scala

I have a java project containing a class MyFileLoader (among others) that successfully loads a file from resources using:
public static List<String> loadFile() {
Path path = System.class.getResource("/my/path/model.bin").getFile().toPath();
return Files.readAllLines(path, UTF_8);
}
and then does some processing.
After adding this project/jar as a dependency in scala, I tried to access MyFileLoader.loadFile. Unfortunately, this gives a java.lang.NullPointerException, as the resource isn't found.
To debug, I ran this command in spark-shell, showing that this resource indeed exists:
scala> getClass.getResource("/my/path/model.bin").getFile
res32: String = file:/some-local-path/my-jar-with-dependencies.jar!/my/path/model.bin
I then tried:
scala> Files.readAllLines(new File(getClass.getResource("/my/path/model.bin").getPath).toPath)
java.nio.file.NoSuchFileException: file:/some-local-path/my-jar-with-dependencies.jar!/my/path/model.bin

Why aren't I able to load the resource these ways?

Since your file is now packaged inside of jar you will need to use Class.getResourceAsStream(). It seems you are trying to read the URL as a regular file which isn't supported (it likely worked before since it wasn't packaged inside of the jar and was able to be loaded as a regular file).

VerifyError Illegal use of nonvirtual function call on Lambda expression in Java 8

I'm working on a project that has recently been introducing lambda expressions. One example goes like this.
public class ExampleItemWriter implements ItemWriter<MyItem> {
public void write(List<? extends MyItem> list) throws RepositoryException {
list.stream().forEach((item)->{
if (item == null) {
}
});
}
}
I don't believe the details inside the forEach() are relevant to the problem, but if they are I can post. There are a few other expressions like this throughout the code that throw the same exception.

We have a few different environments running the same code and only some of them throw this exception. I've spent many hours on this problem and finally posting it here for ideas. The environments look like they have the same jdk 1.8.0_31 and we're using the maven-compiler-plugin 3.2.
Any tips on where we might look? I'm out of ideas. Thanks, /w

The reason could be that the interface is replaced by a version which was compiled on java 8 and rest of the code is on lower version say java 5. There is bug opened for this https://bugs.openjdk.java.net/browse/JDK-8004967
However, I don't think this is the case here since you are using java8 features in ExampleItemWriter and you have to compile it on java8. So there is no question of inconsistent targets. You can still consider rebuilding your entire project on java8.

I copied your write method into another class, replacing MyItem by String and using a regular Exception. So, this worked fine for a list of strings.
So I assume this either has to do with your content of forEach(), or - what was mentioned above - with a version conflict.

MissingMethodException - org.neo4j.kernel.impl.coreapi.schema.IndexDefinitionImpl.createNode() - Groovy

I'm actually stuck on this for several hours..
My code is simple and just want to add several nodes using Labeled index.
Without index stuff (Don't creating createDeferredSchemaIndex ) the code works without a problem.
My exception is:
groovy.lang.MissingMethodException: No signature of method: org.neo4j.kernel.impl.coreapi.schema.IndexDefinitionImpl.createNode() is applicable for argument types: (java.util.LinkedHashMap, [Lorg.neo4j.graphdb.Label;) values: [[tag:START], [MacMorphoTag]]

I know about the signature method that don't match with my parameters but, by the Neo4J code from here: https://github.com/neo4j/neo4j/blob/master/community/kernel/src/main/java/org/neo4j/unsafe/batchinsert/BatchInserterImpl.java
On line 578:
public long createNode( Map properties, Label... labels )
That's exactly what I send from my groovy.
batch = org.neo4j.unsafe.batchinsert.BatchInserters.inserter(store,config)
batch = batch.createDeferredSchemaIndex( macMorphoTagLabel ).on( 'tag' ).create();
...
Label macMorphoTagLabel = DynamicLabel.label( 'MacMorphoTag' );
def Label[] macMorphoTagArray = [macMorphoTagLabel]
if (!tags[previousWordTag.macMorphoTag]) {
tags[previousWordTag.macMorphoTag] = batch.createNode([tag: previousWordTag.macMorphoTag], macMorphoTagArray)
}
What I missing here? I'm using Groovy 2.3.7 + Neo4j 2.1.5
For instance -> My full code: http://pastebin.com/Z98tMDYi problem happen on line 110
My Json file is: http://pastebin.com/xSxZd4ke (as UTF-8 file)

In line 66 you're reassigning the batch variable. Replace
batch = batch.createDeferredSchemaIndex( macMorphoTagLabel ).on( 'tag' ).create();
with
batch.createDeferredSchemaIndex( macMorphoTagLabel ).on( 'tag' ).create();

I'm using java + groovy scripts. Is it possible to change this generated by groovy class names (Script1.groovy, Script777.groovy etc.)? It's hard to find correct script in case of exception:/

Yes, it's possible to set custom name for groovy script. You should use groovy.lang.GroovyClassLoader. For example:
GroovyClassLoader groovyClassLoader = new GroovyClassLoader();
Class<Script> parsedClass = groovyClassLoader.parseClass(scriptText, name);
Script script = scriptClass.newInstance();
script.run()

Error attempting to get var names for namespace in cljunit

I'm working with a project that contains Java classes and Clojure files. The objective is to test Clojure files using java.
I'm using Cljunit for this purpose: https://github.com/mikera/cljunit
The code I use is next:
public class DemoClojureTest extends ClojureTest {
#Override
public List<String> namespaces() {
#SuppressWarnings("unused") ArrayList<String> ns=new ArrayList<String>();
ns.add("com.example.demo.helloWorld");
return ns;
}
}
And the clojure file (helloWorld.clj) is:
(ns com.example.demo.helloWorld
(:use clojure.test))
(deftest test1
(is (= 1 3)))
(deftest test2
(is (= 2 2)))
When I try to execute the DemoClojureTest I get this error:
Error attempting to get var names for namespace [com.example.demo.helloWorld]
java.io.FileNotFoundException: Could not locate com/example/demo/helloWorld__init.class or com/example/demo/helloWorld.clj on classpath:

What I'm doing wrong?

From the stack trace, it looks like the IntelliJ test runner is either running your tests with a classpath that does not include your Clojure source files, or not including them in the build.
Make sure the folder, your Clojure files are in, is under a "Content Root" and marked as a "Sources", or "Test Sources", folder in the module settings.
