kandi X-RAY | jackson-core Summary
This project contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format. The core abstractions are not JSON specific, although naming does contain 'JSON' in many places, due to historical reasons. Only packages that specifically contain word 'json' are JSON-specific. This package is the base on which Jackson data-binding package builds on. It is licensed under Apache License 2.0. Alternate data format implementations (like Smile (binary JSON), XML, CSV, Protobuf, and CBOR) also build on this base package, implementing the core interfaces, making it possible to use standard data-binding package regardless of underlying data format. Project contains versions 2.0 and above: source code for earlier (1.x) versions can be found from Jackson-1 github repo.

QUESTION
I have a doubt with the dependency management in maven central. I have to say that this is a project in initial phase and I am not using my own repository, that's why I have this doubt.
GitHub dependabot tells me that the version I use jackson-databind is vulnerable.
Package com.fasterxml.jackson.core:jackson-databind (Maven) Affected versions >= 2.13.0, <= 2.13.2.0 Patched version 2.13.2.1
...ANSWER
Answered 2022-Apr-15 at 22:21A brief search of maven central reveals that the newest version of jackson-databind is 2.13.2.2.
QUESTION
I'm trying to switch to using Kotlin DSL to get dependencies versions from an object Kotlin file instead of gradle files. When I do a gradle sync it is unable to resolve reference, but I'm able to click on file (Libraries) from build.gradle.kts . I haven't made any other changes to build.gradle or settings.gradle . The issue isn't specific to Jackson and I tried this in multiple projects and read documentation and searched for answers before posting the question.
I get a build.gradle.kts:15:20: Unresolved reference: Libraries
This is the structure of my project
...ANSWER
Answered 2022-Mar-21 at 18:41Are you trying to access ./buildSrc/src/main/kotlin/Libraries.kt in ./buildSrc/build.gradle.kts? Because that's not possible, and isn't necessary.
Basically it's not possible to use ./buildSrc/src/main/kotlin/Libraries.kt in ./buildSrc/build.gradle.kts for the same reason you can't use /src/main/kotlin/Libraries.kt in .//build.gradle.kts. The Gradle build scripts can't use the output of the projects they're trying to build.
However buildSrc is treated as included build, so the contents of ./buildSrc/src/main/... will be available in /build.gradle.kts
It's possible to share versions between ./buildSrc/build.gradle.kts and /build.gradle.kts with Version Catalogs.
The libs.versions.toml file is the easiest way to do this.
In short,
- Use Gradle 7.4+
- Create a
/gradle/libs.versions.tomlfile - Define your dependencies, e.g.
QUESTION
I've created a new Java project in IntelliJ with Gradle that uses Java 17. When running my app it has the error Cause: error: invalid source release: 17.
My Settings
I've installed openjdk-17 through IntelliJ and set it as my Project SDK.
The Project language level has been set to 17 - Sealed types, always-strict floating-point semantics.
In Modules -> Sources I've set the Language level to Project default (17 - Sealed types, always strict floating-point semantics).
In Modules -> Dependencies I've set the Module SDK to Project SDK openjdk-17.
In Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler I've set the Project bytecode version to 17.
Gradle
...ANSWER
Answered 2021-Oct-24 at 14:23The message typically entails that your JAVA_HOME environment variable points to a different Java version.
Here are the steps to follow:
- Close IntelliJ IDEA
- Open a terminal window and check your JAVA_HOME variable value:
- *nix system:
echo $JAVA_HOME - Windows system:
echo %JAVA_HOME%
- *nix system:
- The JAVA_HOME path should be pointing to a different path, then set it to the openjdk-17 path:
- *nix system:
export JAVA_HOME=/path/to/openjdk-17 - Windows system:
set JAVA_HOME=path\to\openjdk-17
- *nix system:
- Open your project again in IntelliJ IDEA
- Make sure to set both source and target compatibility versions (not only the
sourceCompatibility)
You should be able to build your project.
EDIT: Gradle ToolchainYou may need also to instruct Gradle to use a different JVM than the one it uses itself by setting the Java plugin toolchain to your target version:

QUESTION
I'm trying to implement a simple Apache Pulsar Function and access the State API in LocalRunner mode, but it's not working.
pom.xml snippet
...ANSWER
Answered 2022-Feb-07 at 19:16The issue is with the name you chose for your function, "Test Function". Since it has a space in it, that causes issues later on inside Pulsar's state store when it uses that name for the internal storage stream.
If you remove the space and use "TestFunction" instead, it will work just fine. I have confirmed this myself just now.

...ANSWER
Answered 2022-Jan-31 at 10:43As can be seen in the comments of the post, my problem is fixed, so I thought I'd collect a closing answer here to not leave the post pending.
The actual solution: As explained here nicely by @UninformedUser, the issue was that I had conflicting maven package versions in my dependencies. Bringing everything in sync with each other solved the issue.
Incidental solution: As I wrote in the comments above, specifically defining 3.3.0 for the maven-assembly-plugin happened to solve the issue. But this was only chance, as explained here by @Ignazio, just because the order of "assembling" things changed, overwriting the conflicting package.
Huge thanks to both for the help.

Install jackson-core
You can use jackson-core like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jackson-core component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
