The util.jar file is now placed in the output folder. The following outcome is the result of running the Ant file − Running Ant on this file creates the util.jar file for us. Therefore, the above example will be updated as follows − This default behavior can be modified by writing few lines of simple codes in the gradle build file. Modifying jar task from Java plugin The jar task from Java gradle plugin generates jar file without any dependency. Based on the instructions from the Eclipse documentation.
#BUILDING A JAVA JAR FILE HOW TO#
These instructions do not cover how to make an executable jar.

The instructions are for bundling the source code (.java files) into a jar. If we want to make the util.jar an executable jar file, we need to add the manifest with the Main-Class meta attribute. &0183 &32 There are 2 ways to create a Jar file with all dependencies using Gradle. This page shows you how to create a jar file (java archive) using the Eclipse IDE. The output jar file will be placed in the web application lib folder. However, we are excluding the classes that end with the name Test. In this example, we create a jar file called util.jar using the classes from the faxapp.util.* package. The build.dir property in this example, points to the build folder, where the class files for the util.jar can be found. In our case, this is where the util.jar will be placed. Here, the web.dir property points to the path of the web source files. Same as above, except the exclude files are specified using a pattern.Īdvises Ant to overwrite files in the already built JAR file.Ĭontinuing our Hello World Fax Application project, let us add a new target to produce the jar files.īut before that, let us consider the jar task given below. You could add, preserve, or fail the duplicate files.Īdvises Ant to not include these comma separated list of files in the package. While the compress attribute is applicable to the individual files, the keepcompression attribute does the same thing, but it applies to the entire archive.Īdvises Ant on what to do when duplicate files are found. By default, this is set to the base directory of the project.Īdvises Ant to compress the file as it creates the JAR file. The base directory for the output JAR file. The next refinements are to set the default target, for when ant is invoked without parameters, and to.
#BUILDING A JAVA JAR FILE INSTALL#
test will run the JUnit tests and report results while install will place the JAR file in a well-known location ( HOME /bin, in Unix terms). class and create the JAR file for the bank account manager, and clean will remove all of these artifacts. The commonly used attributes of the jar task are as follows − Sr.No &0183 &32 build will compile all the Java code to.

The basic steps are outlined in the Building Java Libraries Simple guide in the Gradle documentation. Creating JAR files with Ant is quite easy with the jar task. Building Java JAR File Building a JAR file using Gradle is super simple - it handles almost all of the heavy lifting for us.
