How to create EAR file using ant build.xml for multi module application?












0















I need to build my multi module application using ant build tool, I am unable find suitable documents. I have few doubts.



Actually our application consists of 7 modules out of which 1 is EAR module(Currently we are building through eclipse without using any build tool).



So my doubt is




  1. can i write a single build.xml i.e in EAR module(EAR project) for building project or do i need to write build.xml for every modules?



  2. and also our project has cyclic dependencies, so is it possible to build using Ant without solving those cyclic dependencies....?



    Thanks in advance

          1. you should have separate build.xmls for all of your modules. build.xml of your ear module should call all other module's build files and finally export the ear with ear task which may look like;






            <property name="build.dir" value="/path/to/your/build-directory/" />
            
<property name="src.dir" value="/path/to/ear-module/" />
            

            
<target name="generate-module-jars">
            
    <!-- this should build module and export module jar to ${build.dir} -->
            
    <ant antfile="module1/build.xml" target="jar" />
            
    <!-- this should build module and export module jar to ${build.dir} -->
            
    <ant antfile="module2/build.xml" target="jar" />
            
    <!-- this should build module and export module jar to ${build.dir} -->
            
    <ant antfile="module3/build.xml" target="jar" />
            
</target>
            

            
<target name="export-ear" depends="generate-module-jars">
            
    <ear destfile="${build.dir}/myapp.ear" appxml="${src.dir}/metadata/application.xml">
            
        <fileset dir="${build.dir}" includes="*.jar,*.war"/>
            
    </ear>
            
</target>




          2. You should reorganize your modules removing cyclic dependencies. But still you can use ivy. Or you can self implement an ant task directly calling eclipse's compiler that can handle cyclic dependencies. (if you are using eclipse)

A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease.
