Can references from the base project be removed from the build projects classpaths?

danton30 — Thu, 31 Mar 2011 01:35:40 +0000

I have a project with the following structure:

_CSBuilder (this contains the build.xml)
   + lib
   + workspace
      + CommonUtils
      + ESBLibraries
      + ... (other projects)

The idea is to build the projects under the "workspace" folder, which are checked out from our CMDB.

Im using the last release from the Hudson link.

However when I run the build.xml, I receive the following:

BUILD FAILED
C:\_CSBuilder\_CSBuilder\build.xml:456: The following error occurred while executing this line:
C:\_CSBuilder\_CSBuilder\build.xml:459: The following error occurred while executing this line:
C:\_CSBuilder\_CSBuilder\build.xml:476: The following error occurred while executing this line:
C:\_CSBuilder\_CSBuilder\build.xml:490: The following error occurred while executing this line:
C:\_CSBuilder\_CSBuilder\build.xml:272: org.ant4eclipse.lib.core.exception.Ant4EclipseException: Could not create jar file from file 'C:\_CSBuilder\_CSBuilder\.project'.

Not sure why the compile task is trying to include the references to the _CSBuilder project (which only contains the build.xml) in the compilation of the CommonUtils project.

Is there a way to remove such reference from the executeJdtProject properties?

Thanks in advance for your help!

Note: After doing some tests yesterday, found an interesting thing. When I downloaded the code cleaning all projects the error is appearing. If I downloaded the code then imported the code to eclipse, If I run the script disabling the cleaning, the error does not appear, however I would expect to be able to compile from the clean state.

Error on compile

danton30 — Sun, 27 Mar 2011 16:29:21 +0000

When running a task to compile a project the following error appears:

BUILD FAILED
C:\CS_Build\CS_Builder\build.xml:356: The following error occurred while executing this line:
C:\CS_Build\CS_Builder\build.xml:359: The following error occurred while executing this line:
C:\CS_Build\CS_Builder\build.xml:377: The following error occurred while executing this line:
C:\CS_Build\CS_Builder\build.xml:391: The following error occurred while executing this line:
C:\CS_Build\CS_Builder\build.xml:180: Class not found: org.ant4eclipse.ant.jdt.ecj.EcjCompilerAdapter

I didnt have any issue with the task until today when opened the project.

I have set up in the class path the org.ant4eclipse_1.0.0.M4.jar, ecj-3.6.jar, org.eclipse.osgi_3.6.0.v20100517.jar and ant-contrib-1.0b3.jar

Thanks in advance for any help!

The task in question is the following:

<target name="compile.project" if="executeJdtProject.source.directories">
 
		<echo>Compiling jdt project '${executeJdtProject.project.name}'</echo>
		<echo>  - source directories -> ${executeJdtProject.source.directories}</echo>
		<echo>  - output directory   -> ${executeJdtProject.default.output.directory}</echo>
		<echo>  - bootclasspath      -> ${executeJdtProject.boot.classpath}</echo>
		<echo>  - classpath          -> ${executeJdtProject.classpath.absolute.compiletime}</echo>
 
		<mkdir dir="${executeJdtProject.default.output.directory}" />
 
		<javac destdir="${executeJdtProject.default.output.directory}" debug="on" 
			bootclasspath="${sun.boot.class.path}"
			compiler="org.ant4eclipse.ant.jdt.ecj.EcjCompilerAdapter">
 
			<src refid="executeJdtProject.source.directories.path" />
			<bootclasspath refid="executeJdtProject.boot.classpath.path" />
			<classpath refid="executeJdtProject.classpath.absolute.compiletime.path" />
 
			<compilerarg value="compiler.args.refid=executeJdtProject.compiler.args" compiler="org.ant4eclipse.ant.jdt.ecj.EcjCompilerAdapter" />

plugin + product build

svkap — Tue, 15 Mar 2011 16:47:06 +0000

Hello.

I've been using the old version of Ant4Eclipse for some time but I decided to update both my target env and Ant4Eclipse. I've used the build script located here: http://www.ant4eclipse.org/node/81 as an example so I can change my current script. Unfortunately I get the following error:

build:
[ant4eclipse:executePluginProject] The content of elements must consist of well-formed character data or markup.

eclipse-ant\macros\a4e-pde-macros.xml:76: org.ant4eclipse.lib.core.exception.Ant4EclipseException: Could not parse document.

Does anybody know how to realize that?

Encoding problem

nazario — Thu, 14 Oct 2010 17:56:33 +0000

I'm building my plugins using Ant4Eclipse, but can't change the encoding of the compiler. I'm compiling in Windows, and Ant4Eclipse seems to be using the operating system encoding. I need source files to be compiled in UTF-8.

How can I accomplish this?

Thanks in advance,
Lucas

Referenced project without classpath entries

joergviola — Fri, 30 Apr 2010 07:15:17 +0000

Hi,

during build I get:

org.ant4eclipse.lib.core.exception.Ant4EclipseException: A precondition has been violated:
at org.ant4eclipse.lib.core.Assure.assertTrue(Assure.java:264)
at org.ant4eclipse.lib.jdt.internal.tools.ClasspathEntryResolverExecutor.resolveReferencedProject(ClasspathEntryResolverExecutor.java:228)
at org.ant4eclipse.lib.jdt.internal.tools.ClasspathEntryResolverExecutor.resolve(ClasspathEntryResolverExecutor.java:168)

seems to the weird situation of a referenced project without classpath entries.
Now I have lots of projects, but a4e does not give me any hint about which project it is complaining.

Build Seam web application

Franta — Fri, 16 Apr 2010 06:25:40 +0000

Hello,
I have got a problem with build Seam web application. Application has theese moduls: Web, EJB, EAR, test. In Ecplipse I click on run button and Ecplise do build and copy application to JBoss AS.
Now, I need do build using ant4ecplise. Could you write me any example, how can I do it?

I try use:
[1]: <buildFeature workspaceDirectory="${workspaceDirectory}"
projectName="SeamApp5"
targetplatformid="eclipse"
destination="${destination}" />

In console, there is an error: A precondition has been violated: hasRole(projectRoleClass) on project...

[2]: <buildPlugin ... /> ... same problem as point [1].

[3]: <copy todir="${destination}" overwrite="true">
<ant4eclipse:pdeProjectFileSet workspaceDirectory="${workspaceDirectory}" projectname="SeamApp5"/>
</copy>

In console, there is an error: Project 'SeamApp5' must have role 'PluginProjectRole' or 'FeatureProjectRole'

I don't know, which task can I use. In Eclipse is project type of the project "SeamApp5": Project (right click on project -> properties -> resource).

Any idea? Thank you!

creating dependency tree

antoinell — Thu, 18 Mar 2010 14:45:19 +0000

I would like to use the code of ant4eclipse to create a dependency tree of the Eclipse projects in a workspace or a specific list of projects inside a workspace.

Does this exist already ?

Otherwise, I could start coding. I have seen that there is a getBuildOrder task. Is the source code of this task a good starting point ?

We could add an ant task to generate the dependency tree, with the option to generate an XML or DOT file to be processed further by a graphing tool. The possibilities offered by the report task of ivy could be offered here too.

ant4eclipse:getUsedProjects crashes in org.ant4eclipse.ant.jdt.type.JdtClassPathContainerType.doValidate

Space008 — Tue, 16 Feb 2010 17:27:32 +0000

My ant script works fine with ant4eclipse 0.5.0.rc1.
Now I'm moving forward to use ant4eclipse 1.0.0.M1.
I updated my script for 1.0.0.M1:
ant taskdef
ant4eclipse:installedJREs & ant4eclipse:jdtClassPathLibrary instead of <path id="..." />
ant4eclipse:getUsedProjects instead of getReferencedProjects (workspaceDirectory instead workspace)

Now in 1.0.0.M1 ant4eclipse:getUsedProjects fails in class: org.ant4eclipse.ant.jdt.type.JdtClassPathContainerType.doValidate(JdtClassPathContainerType.java:101)

I also tried to use org.ant4eclipse_1745.zip for Hudson build 26.

java.util.UnknownFormatConversionException: Conversion = 'R'

rdifrango — Tue, 02 Feb 2010 21:15:52 +0000

Anyone seen this error occur when having class path references

java.util.UnknownFormatConversionException: Conversion = 'R'

Here are the relevant build.xml snippets:

<ant4eclipse:jdtClassPathLibrary name="org.eclipse.jst.j2ee.internal.module.container">
            <fileset dir="../ShareLibraries/testing/" includes="**/*.jar" />
        </ant4eclipse:jdtClassPathLibrary>

<ant4eclipse:getJdtClassPath pathId="build.classpath" workspaceDirectory="${workspace}" projectName="${ant.project.name}" />
