I finally was able to reproduce your issue with Java 11 and Maven 3.8.

As indicated in the question comments, the problem seems to be related to the fact that the Maven surefire plugin is not using the system class loader. Please, consider read the relevant documentation.

You can verify that point using the following plugin configuration:

QUESTION

how come scala code gets compiled with Java?

Asked 2022-Jan-07 at 13:06

I'm trying to understand how Scala code works with Java in Java's IDE. I got this doubt while working with Spark Java where I saw Scala packages too in code and using respective classes and methods.

My understanding says, Scala code need Scala's compiler to convert into Java.class files and then from their onwards JDK do its part in JVM to convert into binaries and do actions. Please correct me if am wrong.

After that, In my spark Java project in eclipse, I couldnt see anywhere where scala compiler is being pointed.

This is my pom.xml

Dependencies ship in class file form. That JavaConverters class must indeed be compiled by scalac. However, the maintainers of janino have done this on their hardware, shipped the compiled result to mavencentral's servers, which distributed it to all mirrors, which is how it ended up on your system's disk, which is why you do not need scalac to use it.

Unsupported JavaFX configuration: classes were loaded from 'unnamed module @...'

Asked 2021-Aug-04 at 18:12

This question seems very similar if not exactly the same. In that question, Slaw's 2nd suggestion involving fixing the module-info for correct module management seems appropriate. But what exactly does that mean; or rather, is there something wrong with my module that javafx is complaining about or is it some other module it's talking about?

This is my module-info.java

...

ANSWER

Answered 2021-Aug-04 at 18:12

I think this might be the answer:

Shading multiple modules into the same jar is not possible, because a jar can only contain 1 module. So, I suppose the shade plugin resolves that problem by removing the module-info files of the dependencies it's using, which means the JavaFX code will not be loaded as a module, and you get a warning like this. I think the only way to get rid of the warning is to not use shading, but keep the JavaFX modules as separate jar files, that you then put on the module path when running the application.

So the obvious option is just to ignore the warning. Javafx warnings rarely seem to indicate anything useful. But it's not always an option to just look away if you distribute your application to other users.

Another (naive) option is to redirect the error stream at launch. It's a little naive because there might be some other error missed..

Your code looks correct. But as the error shows "nested exception is java.lang.IllegalStateException: Client id must not be empty.", you need to check the application.properties again and make sure it's correct.

And the sample needs three dependencies(spring-boot-starter-oauth2-client, spring-boot-starter-web, azure-spring-boot-starter-active-directory), you could try to update your pom with the newer version.

How does the library "Symja" need to be imported with Gradle in order to work with the Elasticsearch server module?

Asked 2021-Apr-29 at 17:51

For a project I wanted to extend Elasticsearch and therefore need to use the package Symja. In the Github for Symja, there is a manual for the usage with Maven provided.

Since the Elasticsearch repository is build with Gradle, I also need to use Gradle instead of Maven. Testing the suggested example Symja project, the following build.gradle (which I basically generated by using gradle init and adjusted a little) imports the library flawlessly:

Missing org.apache.parquet.hadoop.ColumnChunkPageWriteStore(org.apache.parquet.hadoop.CodecFactory$BytesCompressor,org.apache.parquet.schema.MessageType,org.apache.parquet.bytes.ByteBufferAllocator,int) [java.lang.NoSuchMethodException: org.apache.parquet.hadoop.ColumnChunkPageWriteStore.(org.apache.parquet.hadoop.CodecFactory$BytesCompressor, org.apache.parquet.schema.MessageType, org.apache.parquet.bytes.ByteBufferAllocator, int)]

Means you are using the Constructor of ColumnChunkPageWriteStore, which takes in 4 parameters, of types (org.apache.parquet.hadoop.CodecFactory$BytesCompressor, org.apache.parquet.schema.MessageType, org.apache.parquet.bytes.ByteBufferAllocator, int)

It cant find the constructor you are using. That why NoSuchMethodError

According to https://jar-download.com/artifacts/org.apache.parquet/parquet-hadoop/1.8.1/source-code/org/apache/parquet/hadoop/ColumnChunkPageWriteStore.java , you need 1.8.1 of parquet-hadoop

Change your mvn import to an older version. I looked at 1.8.1 source code and it has the proper constructor you need.
