Liferay 7 Dependency Issue with Apache POI

RE: Liferay 7 Dependency Issue with Apache POI

Hi, I'm facing a similiar issue but with the next class "ThemeDisplaySupplier" located in SearchWeb v:4.0.19.I have the next build.gradle file:

compileOnly group: "com.liferay", name: "com.liferay.asset.taglib", version: "4.0.15"
compileOnly group: "com.liferay", name: "com.liferay.comment.taglib", version: "2.0.7"

compileOnly group: "com.liferay", name: "com.liferay.frontend.taglib.dynamic.section", version: "2.0.1"
compileOnly group: "com.liferay", name: "com.liferay.frontend.taglib.form.navigator", version: "3.0.5"
compileOnly group: "com.liferay", name: "com.liferay.frontend.taglib.util", version: "2.0.2"
compileOnly group: "com.liferay", name: "com.liferay.journal.taglib", version: "3.0.1"
compileOnly group: "com.liferay", name: "com.liferay.layout.taglib", version: "4.0.8"
compileOnly group: "com.liferay", name: "com.liferay.site.taglib", version: "2.0.1"
compileOnly group: "com.liferay", name: "com.liferay.portal.search.api", version: "3.7.1"
compileOnly group: "com.liferay", name: "com.liferay.portal.search.web", version: "4.0.19"
compileOnly group: "com.liferay", name: "com.liferay.portal.search.web.api", version: "3.0.4"
compileOnly group: "com.liferay.portal", name: "com.liferay.portal.kernel", version: "4.13.1"
compileOnly group: "com.liferay.portal", name: "com.liferay.util.taglib", version: "4.1.0"
compileOnly group: "javax.portlet", name: "portlet-api", version: "3.0.0"
compileOnly group: "javax.servlet", name: "javax.servlet-api", version: "3.0.1"
compileOnly group: "jstl", name: "jstl", version: "1.2"
compileOnly group: "org.osgi", name: "org.osgi.service.component.annotations", version: "1.3.0"
compileOnly group: 'org.osgi', name: 'org.osgi.annotation', version: '6.0.0';

The error is during deploy phase and it is the trace:
Field publishedFacetFactory cannot be found in component class com.mju.sgntj.comcom.publishdate.portlet.PublishDateFacetPortlet. The field will be ignored.

Kushagra Khanna:

Have you resolved this issue ?

If you really really really need to include the transitive dependencies in your jar, i.e. if you really can't deploy them for some reason or another, option 3 and 4 might be worth trying.

Hi Saleem,

Have you resolved this issue ?
I am facing the same issue, please share steps that you have followed to resolve the same.

Thanks,

David H Nebinger:

maven offers the dependency:tree which will dump the effective dependency tree for a project, but I'm not sure that gradle has anything similar.

Most of the maven repo search sites such as mvnrepository.com will list dependencies of a jar, so you can use that to identify transitive dependencies, also the MANIFEST.MF file of each jar will list dependencies too, so that can be a lot of grunt work but will lead to the same conclusions.

Hello David,

I have been trying to add all the transitive dependencies but some dependencies are unavailable and I cant proceed further. Is there a way where we can configure bnd to just include the jar rather extract it and recompile again.

Exporting the package won't work because you're not providing any of the classes.

I think your problem is not the one you think it is. Likely the issue is an unresolved transitive dependency that has not been satisfied.

How do I find that "transitive dependency" ?

To solve the above error I tried including below:


Export-Package: com.liferay.portal.kernel.* , javax.*

Now the module start and runs without any error. But its doesn't appear in the Application menu where we can drag and drop the portlet. If i remove the added dependency everything works fine and portlet is available to add to a page.

Please let me know whats the issue.

Thanks & Regards
