I am following this documentation for ScalikeJDBCGen, which can generate source code from MySQL schema. However on executing below command I receive ClassNotFoundException.
I can see MySql in my sbt dependencies. Also I tried to run this by removing it from dependencies with the doubt of conflict of 2 versions of same dependencies (See image below). But outcome remains same. How can I fix this?
Terminal
sbt "scalikejdbcGen product Product"

Adding the JDBC driver to project/plugins.sbt should work for you!

I updated the version of the liquibase-maven-plugin from 3.9.0 to the latest. The version they have you. the version given in the tutorial is outdated.
Top module is as follows;
class PE (DataWidth: Int, NumLinks: Int, NumEntries: Int, FifoDepth: Int) extends Module {
val io = IO(new Bundle {
...
})
...
}
I think that this is ordinary style for the chisel3.
I do the following run of sbt to lint the code;
sbt 'test:runMain noc.PEMain'
Then I get bellow error messages;

This is caused at
val io = IO(new Bundle {
val No = Output(Vec(NumLinks, UInt((log2Ceil(NumLinks)).W)))
})
It seem that the main problem is:
attempted to instantiate a Module without wrapping it in Module()
This may rise due to you making a new instance of a class extended from Module but you are probably not wrapping it into one.
For example you in your code you are doing something like:
val test = new module_class
where as you should be doing
val test = Module(new module_class)

Could someone see what is wrong and what is the simple way to generate static html as simple as

in scala with some available scala libraries or apis?
I have been following tutorials on PlayFramework, but it seems that they are all outdated and for older version of Play.
I want to try JUnit test using mysql databse not h2 in-memory database.
I am using ebean ORC (which clearly has different api than it used to have inside play 2.2, and the api is not really well documented).
Anyway I want to try JUnit test on mysql databse, but I am always getting a configuration error.
This is how the JUnit test class looks:
public class ModelsTest extends WithApplication {
public Application app;
#Before
public void setUp() throws FileNotFoundException, IOException {
java.util.Properties externalProps=new java.util.Properties();
externalProps.load(new FileInputStream("resources/test-ebean.properties"));
ServerConfig config = new ServerConfig();
config.setName("test");
config.setDefaultServer(true);
config.loadFromProperties(externalProps);
EbeanServer server = EbeanServerFactory.create(config);
app = Helpers.fakeApplication();
Helpers.start(app);
}
#Test
public void createAndRetrieveUser() {
new User("bob#bob.bob", "admin", "admin").save();
User bob = User.find.where().eq("email", "bob#bob.bob").findUnique();
assertNotNull(bob);
assertEquals("admin", bob.login);
}
#After
public void stopApp() {
Helpers.stop(app);
}

I just started learning play (but actually most of tutorials are outdated) and I have spent more time trying to configure it to run than actually coding. I guess I should look up another framework.
You don't need to set up a whole database just for testing (you are free to, of course). Play relies strongly on In-Memory databases (e.g. during development) and you can utilize this also in your tests:
#Test
public void findById() {
running(fakeApplication(inMemoryDatabase("test")), () -> {
User bob = User.findById(21l);
assertEquals("bob#bob.bob", bob.email);
assertEquals("admin", bob.login);
});
}
On the other hand if you really want to test the database access code you can go as far as creating a Database test object:
Database database = Databases.createFrom(
"com.mysql.jdbc.Driver",
"jdbc:mysql://localhost/test"
);
Which again can be in-memory:
Database database = Databases.inMemory(
"mydatabase",
ImmutableMap.of(
"MODE", "MYSQL"
),
ImmutableMap.of(
"logStatements", true
)
);
Just don't forget to release the resources after the test:
#After
public void shutdownDatabase() {
database.shutdown();
}

try below code snippet
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>1.6</version>
For java 8 you can try with the higher versions
This is an issue with versioning. Try using a different version of jaxb2-maven-plugin until you get this to pass.
I use Linux and resolve this issue by -
export JAVA_HOME=/usr/lib/jvm/{java version}
Example -
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
