I am considering converting an Ant/Ivy project to Ant/Maven-Ant-Tasks. I do not want to use Maven by itself because I need more control over the build process.
Is there any way for the Ant build.xml file inherit properties set in the pom.xml file?
I have been creating a generic build.xml file that can be used across several projects and loads a project-specific project.properties file, but it would be nicer if I could put all of those properties in the pom.xml file.
Thanks.
I use the XMLProperty ant task to parse and copy those properties
http://ant.apache.org/manual/Tasks/xmlproperty.html
<xmlproperty file="<your pom location>" keepRoot="false"/>
<property name="test" value="${properties.test}"/>
Another option, if you use the maven Antrun plugin to run the build, the properties will be available to use in the build file

I am using IntelliJ IDEA CE 2020.3 to build a simple JAR file. After the build, I'd like to copy the created JAR to a library directory.
I am using the Ant plugin that comes bundled with the IDE. I can't seem to find the underlying Ant build/control files that make the whole thing work. I assume Ant uses the .XML files that are part of the IDE's project settings, but this is unclear.
In any case, is there a way to add the "copy" step that I mention above?
Do I have to either use the built-in Ant or take it over completely myself?
Can I edit the default that ships with the IDE?
All,
So after some experimenting, I found that if I manually create the build.xml file, I can execute post-build steps. For my example here, I created the following, simple build.xml and added it to the top-level IntelliJ project directory (where the .iml file lives):
build.xml (manually created)
<project name="mylib" default="copy-file">
<target name="copy-file">
<copy file="out/artifacts/mylib_JAR/mylib.jar" tofile = "./mylib.jar" />
</target>
</project>
Note that the directories are relative to the project directory.
IntelliJ IDEA enabled me to add the copy-file task to augment the default, built-in build. To configure your tasks via the IDE, open the Ant tool window via the View/Tool Windows/Ant main menu item.
I hope this helps someone out there!
I have a project that uses IVY. My build script resolves the dependencies well.
I have a library (lets call it Project_libs) configured in IntelliJ iml file so that when I deploy the application the jars get published to the server.
I have an ant task ide-setup which copies the necessary jars from Ivy local repo to Project_libs so these jars are available to IDEA during deployement.
Lets say I make changes to a common library like utils.
Build the common library.
Go to the projects that declared this common library as a dependency and run ide-setup
Then start the server.
Is there a direct way in which I can configure IDEA to read the dependencies from the ivy.xml file instead of doing this convoluted process of setting up the whole thing.
I don't know anything about InelliJ IDEA, but I believe you could accomplish what you want using ant and IVY. From the IVY documentation
<ivy:buildlist reference="build-path" ivyfilepath="ivy/ivy.xml" leaf="mymodule">
<fileset dir="projects" includes="**/build.xml"/>
</ivy:buildlist>
Builds a list of build.xml files sorted according to the ivy.xml files found in an
ivy directory relative to those build files. Only build.xml files of modules which
have dependencies (direct or transitive) on mymodule are put in the result list.
So if you set leaf equal to utils, it could return you a list of build.xml files that depend on utils in dependency order. Then all you would have to do is go through those build.xml files in order and invode their build process (probably through a subant call)
Is it possible to convert project .classpath file to pom.xml after converting a simple web application project to maven project? Because if my project uses many jars and I want to convert it to maven then I will do configure->convert to maven but then it is not possible to add all the jars dependencies in pom.xml manually. So is there any tool to convert this.
First there is no tool to do such things. The problem is usually that you have a larger number of dependencies which you don't need to put into the pom.xml file, cause Maven handles transitive dependencies which means you only need to add only direct dependencies. The best thing is to look at the current projects jar files and try to find them in Maven Central and cut&paste the information form the search output into your pom. And of course test the build via Maven on command line.
I have pom.xml file that contains dependencies and files to checkout from svn so there is no no need to generate project. I just need these libraries and those files, so is there any way to get them without generating a project with maven directory structure?
I'm not sure from your question what do you want. If you have pom.xml file and you want to download all dependencies defined in it, you can call
mvn dependency:copy-dependencies
For more options look maven copy-dependencies task page
If you are asking how to create pom that will contain no code, but only dependencies, you can do that by specifying pom packaging.
At the end of my ant build id like it to call the equivalent of the command line call
mvn install:install-file -Dfile=my.jar -DgroupId=com.company.project -DartifactId=my_project -Dversion=1.0 -Dpackaging=jar -DgeneratePom=true
so that it will add the newly built jar to a maven repository which another project will rely on.
Ive tried using the maven-ant-task and have added the maven-ant-task jar to the ant built project and the following code to the build.xml:
<target name ="minstall" depends="jar">
<artifact:pom id="maven_install" file="maven_install.xml" />
<artifact:install file="${out.dir}/my_project.jar">
<pom refid="maven_install"/>
</artifact:install>
</target>
but seem to be missing something as it wont work for me. To begin with i get the error in the build.xml (ant build file) saying
The prefix "artifact" for element "artifact:pom" is not bound.
What am I doing wrong. I am fairly new to ant?
On a realted question what is the purpose of the associated POM file? I would not normally have a POM in this project as it is an ant build
Perhaps maven-ant-task jar is not installed, i.e. not in your ant CLASSPATH. You can follow this instruction for this.
As mentioned previously, you need to make sure the tasks are defined in your ant script, and the artifact namespace is understood.
The POM file is used (in this case) to tell the Maven repositories the dependencies of the JAR you are putting in the repository. The POM should also specify the JAR's identification information (groupId, artifactId, version number, license, etc.).
Strictly speaking, you do not need an external POM, you could define the information in your build.xml file as follows:
<!-- Assuming tasks defined, and 'artifact' namespace exists -->
<artifact:pom id="maven_install" groupId="com.whatever" artifactId="some-jar"
version="1.0" packaging="jar">
<dependency groupId="..." artifactId="..." version="..."/>
<dependency groupId="..." artifactId="..." version="..."/>
<license name="apache" url="http://www.apache.org"/> <!-- can be omitted -->
</artifact:pom>
<target name ="minstall" depends="jar">
<artifact:install file="${out.dir}/my_project.jar" pomRefId="maven_install"/>
</target>
When you install the JAR in the 'minstall' task, the POM should be generated with the appropriate dependencies in the local Repository.
That message means you are missing an xmlns:artifact attribute in your build.xml. Have a look at the installation page in the docs for an example.
As to the purpose of the POM file, it's mostly metadata so that maven can figure out dependencies properly. In a real maven build it also describes how to build, test and package. But in your case all that is done by ant instead.
I think that it makes no sense to put such commands in Ant's build.xml. If you want to have your jar file installed in your maven repo just use mvn install command.
Besides that, I guess that you are somehow confusing the purpose of Maven and Ant tools in your project. What I'd suggest is to use Maven as your main build tool. You can configure invokation of Ant targets in your POM file if you really need that. Personally, I think it is the best solution to have Ant called by Maven. Maven goals (such as clean, test, package, install and so on) are very simple to use and powerful (I guess that you can read it in every Maven tutorial).
