To create the ButtonDemo.app package, use theappbundler tool. The appbundler is not shippedwith the 7u6 version of the Oracle JDK for the Mac. You candownload it from the Java Application Bundler project on java.net. There is alsoAppBundler Documentation available.
In order to distribute a Java application, you want to avoiddependencies on third party software. Your app packageshould include the Java Runtime Environment, or JRE. In fact, theApple Store requires the use of an embedded JRE as a prerequisitefor Mac App Store distribution. The runtime sub-element ofthe task specifies the root of the JREthat will be included in the app package.
Create a fresh version of ButtonDemo.app, using theant bundle-buttonDemo command. The resulting versionincludes the JRE in the app package. You can confirm this byexamining the Contents/PlugIns directory inside of theapp package.
I write amateur Java scientific applications which I provide freely for a small audience. (Probably I am the main user.) Most of them are still compiled under Java 1.6 where they run fine on Mojave either as jar files or as applications with the standard package contents structure shown below.
The API of IvyDE has been stabilized so that third party plugins can rely on it, while still not complete, and still not advertised as stable in Ivy, support of OSGi has been added, javadoc and source attachement can be edited now one by one, improved stability of the resolve process, improved logging for easier debugging.
This part of the tutorial shows how you can create a distributable application in the IDE and then run that application from outside of the IDE. We will package the application in the form of an executable JAR file.
Clone your forked simple-java-maven-app repository (on GitHub) locally toyour machine. To begin this process, do either of the following (where is the name of your user account on your operating system):
Save your edited Jenkinsfile and commit it to your localsimple-java-maven-app Git repository. E.g. Within thesimple-java-maven-app directory, run the commands:git add .thengit commit -m "Add initial Jenkinsfile"
Save your edited Jenkinsfile and commit it to your localsimple-java-maven-app Git repository. E.g. Within thesimple-java-maven-app directory, run the commands:git stage .thengit commit -m "Add 'Test' stage"
Save your edited Jenkinsfile and commit it to your localsimple-java-maven-app Git repository. E.g. Within thesimple-java-maven-app directory, run the commands:git stage .thengit commit -m "Add 'Deliver' stage"

The following program create and write to a text file "out.txt" (via java.util.Formatter), and read it back (via java.util.Scanner). I do the write first so that you can check the location of the exteranl files under eclipse, which is at the project base directory, at the same level as the "src" and "bin".
Your AWS Lambda function's code consists of scripts or compiled programs and their dependencies. You use a deployment package to deploy your function code to Lambda. Lambda supports two types of deployment packages: container images and .zip file archives.
This page describes how to create your deployment package as a .zip file or Jar file, and then use the deployment package to deploy your function code to AWS Lambda using the AWS Command Line Interface (AWS CLI).
To create a deployment package, compile your function code and dependencies into a single .zip file or Java Archive (JAR) file. For Gradle, use the Zip build type. For Apache Maven, use the Maven Shade plugin.
To keep your deployment package size small, package your function's dependencies in layers. Layers enable you to manage your dependencies independently, can be used by multiple functions, and can be shared with other accounts. For more information, see Creating and sharing Lambda layers.
This build configuration produces a deployment package in the build/distributions directory. The compileJava task compiles your function's classes. The processResources task copies the Java project resources into their target directory, potentially processing then. The statement into('lib') then copies dependency libraries from the build's classpath into a folder named lib.
If you use the appender library (aws-lambda-java-log4j2), you must also configure a transformer for the Maven Shade plugin. The transformer library combines versions of a cache file that appear in both the appender library and in Log4j.
To update a function's code with the AWS Command Line Interface (AWS CLI) or AWS SDK, use the UpdateFunctionCode API operation. For the AWS CLI, use the update-function-code command. The following command uploads a deployment package named my-function.zip in the current directory:
If your deployment package is larger than 50 MB, you can't upload it directly. Upload it to an Amazon Simple Storage Service (Amazon S3) bucket and point Lambda to the object. The following example commands upload a deployment package to an S3 bucket named my-bucket and use it to update a function's code:
You can use AWS SAM to automate deployments of your function code, configuration, and dependencies. AWS SAM is an extension of AWS CloudFormation that provides a simplified syntax for defining serverless applications. The following example template defines a function with a deployment package in the build/distributions directory that Gradle uses:
To create the function, use the package and deploy commands. These commands are customizations to the AWS CLI. They wrap other commands to upload the deployment package to Amazon S3, rewrite the template with the object URI, and update the function's code.
The following example script runs a Gradle build and uploads the deployment package that it creates. It creates an AWS CloudFormation stack the first time you run it. If the stack already exists, the script updates it.
On Linux you have to unzip it before you can start it.On Mac the installer is delivered as a packaged application and can be installed and started via regular Mac installation procedures.On Windows and Mac you can run it directly via the delivered executable / package application.
A good naming convention is to use the same name for the top level package and the project.For example, if you name your project com.example.javaproject you should also use com.example.javaproject as the top-level package name.
Create the following Tester class in the *.main package.This is a simple class without the usage of any unit testing framework like JUnit.The Eclipse editor should mark the created class with an error because the required import statements are missing.
The Package Explorer view allows you to display the associated file from the currently selected editor.For example, if you are working on the Foo.java file in the Java editor and switch to the Java editor of the Var.java file, then the corresponding file will be selected in the Package Explorer view.
To add import statements to your code, you can use the Organize Imports action (shortcut: Ctrl+Shift+O).If there are several alternatives, Eclipse suggests all available packages and the user has to select the right one.
If you never use certain packages, for example AWT or Swing, you can exclude these packages from Eclipse via the Window Preferences Java Appearance Type Filters setting.
Please note that Eclipse shows (in its default configuration) only the packages that are used in the current workspace.If you want to exclude standard Java packages, you have to create at least one Java project.
JAMA is a basic linear algebra package for Java. It provides user-levelclasses for constructing and manipulating real, dense matrices. It ismeant to provide sufficient functionality for routine problems, packaged in away that is natural and understandable to non-experts. It is intended toserve as the standard matrix class for Java, and will be proposed assuch to the JavaGrande Forum and then to Sun.A straightforward public-domain reference implementation has been developed bythe MathWorks and NIST as a strawman for such a class. Weare releasing this version in order to obtain public comment. There is noguarantee that future versions of JAMA will be compatible with this one.
A sibling matrix package,Jampack,has also been developed at NIST and the University of Maryland. Thetwo packages arose from the need to evaluate alternate designs forthe implementation of matrices in Java. JAMA is based on a singlematrix class within a strictly object-oriented framework. Jampackuses a more open approach that lends itself to extension by theuser. As it turns out, for the casual user the packages differprincipally in the syntax of the matrix operations. We hope you willtake the time to look at Jampack along with JAMA. There is much tobe learned from both packages.
JAMA was originally created as a proof-of-concept; a potential primary linear algebra package that could be adopted for Java.As such, it is no longer actively developed to keep track of evolving usagepatterns in the Java language, nor to further improve the API.We will, however, fix outright errors in the code.
Would you like to package your Java application so that anyone can install it and run it without first having to install Java? Would you like to distribute your work just like any other native application for Mac, Linux and Windows? In this article I show how I did this for my Open Source project, what problems I encountered, and the solutions that I found. I hope that my experience will be a useful guide to anyone else attempting this in their own project. 2b1af7f3a8
