How add antlib declaration to project in eclipse? - eclipse

I have created project named "antt" to test ant with Migration tool from eclipse.
I have created java project in eclipse and try run "test" from there.
"test" in build.xml:
<!-- Test out deploy and retrieve verbs for package 'mypkg' -->
<target name="test">
<!-- Upload the contents of the "mypkg" package -->
<sf:deploy username="${sf.username}" password="${sf.password}" sessionId="${sf.sessionId}" serverurl="${sf.serverurl}" maxPoll="${sf.maxPoll}" deployRoot="mypkg" rollbackOnError="true"/>
<mkdir dir="retrieveOutput"/>
<!-- Retrieve the contents into another directory -->
<sf:retrieve username="${sf.username}" password="${sf.password}" sessionId="${sf.sessionId}" serverurl="${sf.serverurl}" maxPoll="${sf.maxPoll}" retrieveTarget="unpackaged" packageNames="MyPkg"/>
</target>
Error:
Buildfile: C:\SF\workspacenew\antt\build.xml test:

Refer to my answer over here,
Create a lib directory in the root of your project and place the maven-ant-tasks.jar file inside it.
Include the import statement in your build.xml
<path id="maven-ant-tasks.classpath" path="lib/maven-ant-tasks-2.1.3.jar" />
<typedef resource="org/apache/maven/artifact/ant/antlib.xml" uri="antlib:org.apache.maven.artifact.ant" classpathref="maven-ant-tasks.classpath" />
Hope this helps.

Ant Build: "Failed to create task, Cause: name is undefined"

I get this error when I try running an Ant Build:
Problem: failed to create task or type http://com.ibm.adapter:createProject
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet
I checked the Runtime JRE (Run in the same JRE as the workspace).
It seems like it can't find the right jar, so I added it (com.ibm.adapter.command) in the Ant Home Entries, but it doesn't work anyway.
Here is the script (even if there shouldn't be problems in this because in another computers worka, I think the problem is only about RAD configuration)
<project default="CreateRigaVariazioneSostituzione" name="/EssigIntegrazione/RigaVariazioneSostituzione.xml" xmlns:adapter="http://com.ibm.adapter">
<property name="debug" value="true"/>
<property name="projCpy2Java" value="EssigIntegrazione"/>
<target name="CreateRigaVariazioneSostituzione">
<adapter:createProject projectName="${projCpy2Java}" projectType="Java" sourceFolder="/src"/>
....
</target>
</project>
Do you know how to fix this?
Install J2C Connector from IBM Installation Manager

Problem: failed to create task or type projectImport

I'm quite new with ANT to build an Eclipse (Oxygen) project. I'm using existing build.xml file which previously written in RAD environment.
Here is my build.xml task;
<foreach
list="${projects.name}"
param="project"
target="import-project" />
<target name="import-project">
<!-- Debug information -->
<echo message="project.name=${project}" />
<echo message="projectLocation=${rad.workspace}\${project}" />
<projectImport
projectName="${project}"
projectLocation="${rad.workspace}\${project}" />
<echo message="projectImport ${project} done" />
</target>
And here is the error
BUILD FAILED
Problem: failed to create task or type projectImport
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
I don't know whether projectImport is available in Eclipse or only in IBM RAD. But if the task is available in Eclipse, do you have any idea why task is failed and if the task only available in IBM RAD, what are the tasks available for me to import project to current workspace.
Thanks
projectImport is IBM RAD only. I don't know of any standard Eclipse equivalent.
Standard Eclipse only provides a very small number of Ant tasks and they all start with eclipse.. See here for the Eclipse tasks list.

Worklight ant tasks for deployment

I am using this documentation.
It tells me to do a ant target like this.
<target name="Deploy App">
<app-deployer deployable="${build.apps.dir}/app.wlapp"
worklightServerHost="http://${customConfig.worklightServer.host}:${customConfig.worklightServer.port}/${customConfig.runtime}"
userName="admin" password="admin" />
</target>
However when I run this target it tells me that app-deployer task is deprecated and I should use something else.
The entire message is below:
[app-deployer] The Ant task <app-deployer> is no longer supported.
[app-deployer] You need to replace this invocation with an invocation of the <wladm> Ant task, like this:
[app-deployer] <taskdef resource="com/worklight/ant/deployers/antlib.xml">
[app-deployer] <classpath>
[app-deployer] <pathelement location="buildTools\buildJars\worklight-ant-deployer.jar"/>
[app-deployer] </classpath>
[app-deployer] </taskdef>
[app-deployer] <wladm url="** URL of Worklight administration services **" user="admin" password="admin">
[app-deployer] <deploy-app runtime="** project runtime name **" file="app.wlapp"/>
[app-deployer] </wladm>
[app-deployer] where values between ** markers are to be filled in.
The version of the worklight ant deployer I'm using is this.
[echo] Worklight Ant task version 6.2.0.00.20140613-0730
Nevertheless, when I create a target with wladm it tells me that
Problem: failed to create task or type wladm
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
The most frequent causes for said error message "failed to create task or type wladm" are:
The <taskdef> has not been executed at this point, in the current Ant script. You may have it in a different target, that is not executed before the current target. The fix is to list it in a common initialization target, or outside of any targets, directory under <project>.
The <taskdef> refers to a nonexistent file or to an older version of worklight-ant-deployer.jar than 6.2.0.
The <taskdef> loads resource="com/worklight/ant/defaults.properties", but in 6.2 it needs to load resource="com/worklight/ant/deployers/antlib.xml".
Not exactly an answer to your question but if you do not need Ant, you can use wladm in command line. See doc at https://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.appadmin.doc/admin/r_wladm_program_app_commands.html
The wladm command is in [WorklightInstallDir]/shortcuts

Checkstyle Error in eclipse: cannot initialize module FilesFilter - Unable to instantiate FilesFilter

I am using checkstyle 5.7
I have written a custom FilesFilter as explained in the checkstyle documentation below,
http://checkstyle.sourceforge.net/writingfilters.html
As suggested in the documentation, I have written a java file and added an entry for it under "Checker" module in my config xml file.
So, this custom filter is supposed to ignore all files containing string "Test" in it's file name.
<module name="com.mycompany.myproject.filters.FilesFilter">
<property name="files" value="Test" />
</module>
Due to this entry in the config file, the check style is not loading in eclipse and gives following error,
cannot initialize module FilesFilter - Unable to instantiate
FilesFilter
Please help.
I think there is no straight solution for this yet. Or may be there is, if you are prepared to invest hours of your time.
Here's what I did as a workaround.
In eclipse, to disable checkstyles for a package (e.g. Test package in my case),
Go to, Project -> Properties -> Checkstyle
On Checkstyle Main tab, there is section "Exclude from checking.." with a set of check boxes.
Select the check box "files from packages:".
Click the "Change.." button in the right hand corner or just double click on "files from packages:"
Select the package you want Checkstyle to ignore. In my case I selected com/myproject/test/ package, and that was it. Checkstyle ignores all files in the test package.
If you are using Checkstyle as an ANT task, you may use excludes option as explained in the following code,
<target name="applyCheckStyle" depends="build" description="--> apply check style to all java files, excluding test package.">
<checkstyle config="${checkstyle.config}">
<fileset dir="${src.dir}" includes="**/*.java" excludes="**/test/**" />
<formatter type="plain" />
<formatter type="xml" toFile="${build.dir}/checkstyle_errors.xml" />
</checkstyle>
</target>
This worked for me :)

Ivy fails to resolve a dependency, unable to find cause

While using ivy:retrieve, it fails to resolve the dependency that should be downloaded. The output looks like this:
Buildfile: C:\Users\Simon\workspace\apollo\build.xml

ANT cannot find the ivy jar. Needs to be downloaded, extracted, and the ivy-x.y.z.jar placed into one of the following locations:
$ANT_HOME/lib
$HOME/.ant/lib
Enabling ivy
Ivy is packaged as an antlib, so to enable it you need to do the following
1)
Declare the ivy namespace at the top of the build file
<project ..... xmlns:ivy="antlib:org.apache.ivy.ant">
2)
Include the ivy jar in one of the ant library directories
Your error message indictates some of the possible locations for antlibs:
This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
-C:\Users\Simon\eclipse\plugins\org.apache.ant_1.8.2.v20120109-1030\lib
-C:\Users\Simon\.ant\lib
-a directory added on the command line with the -lib argument
Note:
The beauty of an antlib is that you don't need to perform the taskdef (It's optional if you want to place the ivy jar in a non-standard location)
How to bootstrap a build
Even though ivy is an ANT sub-project, for some inexplicable reason ivy is not packaged with ANT....
I normally include the following target in my build files to setup a new environment:
<target name="bootstrap" description="Used to install the ivy task jar">
<mkdir dir="${user.home}/.ant/lib"/>
<get dest="${user.home}/.ant/lib/ivy.jar" src="http://search.maven.org/remotecontent?filepath=org/apache/ivy/ivy/2.2.0/ivy-2.2.0.jar"/>
</target>
It downloads the ivy jar from Maven Central.
Since all other ANT tasks can subsequently be downloaded using ivy, few people object to this little piece of ugliness at the top of the build file.
If you can't put the ivy libs in the classpath for ant you will need to define it yourself:
<path id="ivy.lib.path">
<fileset dir="path/to/dir/with/ivy/jar" includes="*.jar"/>
</path>
<taskdef resource="org/apache/ivy/ant/antlib.xml"
uri="antlib:org.apache.ivy.ant" classpathref="ivy.lib.path"/>
This bit is missing from the getting started tutorial, but listed here: http://ant.apache.org/ivy/history/2.2.0/ant.html
When you Run Ant task, in the classpath ensure that ivy.jar is there. In the eclipse -> Run As-> Ant Build -> Edit configuration -> Classpath tab. Even though Eclipse would have the ivy.jar in the ANT Home, for some reason it's not called.
I had a similar problem on MacOSX (10.11.6 El Capitan). I installed ant and Ivy with the Brew package manager.
One additional way is to define it manually using the -lib option, e.g.:
ant clean compile -lib /usr/local/Cellar/ivy/2.4.0/libexec/ivy-2.4.0.jar
Even after adding ivy jar to the ant lib, it was not being picked up. Selecting the ANT_HOME again in Preferences->Ant->Runtime will cause the lib dir to be refreshed, and any libraries you have added there to be taken up.
