            maven-checkstyle-plugin failed to parse Java 'record'
            Asked 2022-Mar-16 at 16:42

            I'm trying to setup checkstyle in our project - but seems like Maven (v3.8.3) or maven-checkstyle-plugin (v3.1.1) itself are not aware of Java 14's record (we use Java 17).



            Answered 2022-Mar-16 at 16:42

            The plugin by default comes with Checkstyle version 8.29. Try explicitly defining the CheckStyle version (plus a small version bump to 3.1.2). For example, with version 9.2:

            What is a Javadoc summary fragment?
            Asked 2021-Feb-19 at 14:17

            I am trying to adhere to Java Style Guide as suggested by Error Prone.

            Section 7.2 The summary fragment states the following:

            Each Javadoc block begins with a brief summary fragment. This fragment is very important: it is the only part of the text that appears in certain contexts such as class and method indexes.

            This is a fragment—a noun phrase or verb phrase, not a complete sentence. It does not begin with A {@code Foo} is a..., or This method returns..., nor does it form a complete imperative sentence like Save the record.. However, the fragment is capitalized and punctuated as if it were a complete sentence.

            Here is what I would like to know:

            • What exactly is a summary fragment? It is stated that every Javadoc block begins with it and that it is text, but is there more documentation somewhere that I might read to get a better understanding about it?
            • Why is the summary fragment very important? It is stated that it appears in class and method indexes, but I am not sure I understand what that means or why it is important. My best guess would be that it is a way to mark classes and it's members in such a way where it would be easier to search them.
            • Where can I find and read the summary fragment? I am using IntelliJ IDEA, so I know how to access Javadoc for classes and members in code via inspection, but is there a way to list all available summary fragments?


            Answered 2021-Feb-19 at 14:17

            Your first two questions are answered here:

            • What exactly is a summary fragment?

            The first sentence of each doc comment should be a summary sentence, containing a concise but complete description of the API item. This means the first sentence of each member, class, interface or package description.

            • Why is the summary fragment very important?

            The Javadoc tool copies this first sentence to the appropriate member, class/interface or package summary. This makes it important to write crisp and informative initial sentences that can stand on their own.

            • Where can I find and read the summary fragment?

              • Method Summary is a table, consisting of three (in some versions, combined in two) columns: "Modifier and Type", "Method", and a "Description". It briefly describes methods' functionality, i.e. - the API;HashMap was chosen merely for the sake of demonstration example.
              • Index is a web page, indexing entire API of the particular Java build.

            Both, "Method Summary" and "Index", are part of the Java doc.



            h2 database persists data but resets on application start
            Asked 2021-Jan-26 at 10:18

            I have a basic test for an embedded database that I'm trying to get working for a java project. As it stands now I am able to save rows to the database with my entity repository object, and after the app finishes running, I can connect to the database with intellij and see those rows are still there. But then, if I comment out the save methods and run it again, when I check the database after it finishes, the database is empty.

            Angular requests blocked by CORS policy only under certain conditions

            Answered 2021-Jan-08 at 15:03

            Downloaded tutorial and it was working out of the box.

            Now to the problem, it is possible to recreate the problem without adding your code by performing a hard refresh of the Hello World page after login.

            The reason for this, is that the author of this tutorial has not included code for storing credentials in localStorage. Hence, when page is reloaded, client app looses credentials stored in state, and pre-flight requests are denied which in turn causes CORS-error.

            So, there is no error, just some code missing in order to make it work according to your requirements.

            Maybe ask a new question on how to persist credentials to localStorage in Angular (I'm not that good with Angular).

            I created dynamic project by using Eclipse. In this project , I have added the hibernate Configuration for mysql database. I am using the servlet for crud operations. I know in maven project the required dependency can be added but not for web applications. I have added the Java.persistance jar files into lib folder. Here is the project structure..

            Here is the Hibernate code.



            Answered 2020-Dec-25 at 23:00

            As @andrewjames pointed out, you need to download the JAXB-API library and an implementation, they are required by Hibernate.

            Although you do not use Maven for dependency management, you can download the corresponding artifacts by clicking in the jar link that you can find in the Files row in the HTML table presented in the artifact page.

            You need to download:

            You already have javax.activation in your dependencies. It is required by JAXB-API.



            Checkstyle ConstantName rule kicks in for things that are not really constant
            Asked 2020-Sep-29 at 21:00

            I would like to check that my field names are uppercase only for fields that meet my preferred definition of "constant", as stated in Google's Java Coding Guidelines.




            Answered 2020-Sep-29 at 21:00

            Not really. Checkstyle would have to execute the code. For instance, private static final Map myMap = Map.of("One", "Blue", "Two", "Red"); is an immutable value.

            One thing you can do is tell Checkstyle that it should not enforce the naming scheme on private fields:

            This error is not related to Spring Framework or Spring Boot. The root cause is your MySQL configuration.

            TLRD: you need to grant access to the root user from localhost. The same issue was asked and answered many times on StackOverflow already 1, 2, ...
