 This seems to be an issue with JLine2 being built with JDK9+, but being used on JDK8. If you're on bionic, try this PPA for jline2: https://launchpad.net/~lokkju/+archive/ubuntu/java-compat/

(or just download and install https://launchpad.net/~lokkju/+archive/ubuntu/java-compat/+build/16458066/+files/libjline2-java_2.14.6-1ubuntu1~bionicppa1_all.deb via dpkg)

You can verify jline2 is the problem by running scala -Ydebug, and looking for ByteBuffer class not found error.

Extracting structure failed --- Error while importing SBT project

 I have used the following plugin

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.8.2") 

 Got the following error.

When  i change the plugin version to the following then everything is working fine.

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.9.2")

view the library dependencies (as you would with Maven) rather than the task dependencies (which is what inspect tree displays)

 If you want to actually view the library dependencies (as you would with Maven) rather than the task dependencies (which is what inspect tree displays), then you'll want to use the sbt-dependency-graph plugin.

Add the following to your project/plugins.sbt (or the global plugins.sbt).

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.9.2")

Then you have access to the dependencyTree command, and others.

error: src refspec master does not match any. error: failed to push some refs to 'git url'

 

7 Ways to improve your programming skills

 In this era of continuous advancements in the software industry, it is important for coders to focus on the improvement of their programming skills. Upskilling, reskilling, and practice are some of the few options that software professionals follow to keep pace with the rapid improvements. If you aspire to become a successful programmer, imbibe the below-mentioned tips that will help you enhance your programming skills precisely.

1. Improve your learning method
Learning is an art and this art is a quality in some from birth while the rest of the population earns it. As a programmer, you might feel overwhelmed from the similar problem solving tasks. Therefore, it is necessary to include entertaining techniques to learn effectively like flashcards, online quizzes, algorithmic puzzles, designing creative apps etc. Always give yourself time to remember the concept rather than just referring notes. Enjoy coding or you will feel burdened by the concepts.

2. Gain fluency in debugging
Debugging is an integral part of programming. When a programmer compromises basic concepts of debugging, they waste precious time and efforts on searching bugs. This is why, debugging techniques including divide and conquer, and proper usage of logs and debuggers should be crystal-clear in your head.

3. Read other developer’s code
Before considering yourself a master already, see how a master creates a code. In simple words, browse through GitHub repositories, learn how other developers have written their code and make your own judgement on how to add quality in the code. This is how one can master coding.

4. Write readable code
As stated by Martin Fowler, “any fool can write code that a computer can understand. Good programmers write code that humans can understand”. A good programmer should write code that are readable and understandable as -

• It will help you debug your code easily
• It will allow other developers to understand your code effortlessly.

5. Work on projects
Search for an app to build, learn how to get started, and work on it. I am not asking you to add quality but at least challenge yourself and see how bonded you are with coding concepts. You will be able to judge your weak points and get a chance to improve.

6. Master one tech stack
Trying to learn every other tool, framework, and programming language is good for professionals who have just begun their career. However, once you have gained familiarity with almost all professional tools, it is recommended to pick one technology stack and master at it. Proficient professionals can attract excellent and startling opportunities.

7. Have curiosity
Your curiosity to learn more and more may get you hired. A good recruiter hires candidates who can contribute to the company's long-term growth rather than the one who plans to use the known skills on
