Liferay Portal 7: Service Builder Broken

[Fuad Efendi, módosítva 9 év-val korábban]

Hi,

After recent refactoring and moving Service Builder outside of portal-impl.jar it is broken.
I spent many hours on a research but I cannot find the cause.

I added "System.out.println()"

	private void _createModelClp(Entity entity) throws Exception {
		if (Validator.isNull(_pluginName)) {
			return;
		}

		JavaClass javaClass = _getJavaClass(
			_outputPath + "/model/impl/" + entity.getName() + "Impl.java");

		Map<string, javamethod> methods = new HashMap&lt;&gt;();

		for (JavaMethod method : javaClass.getMethods()) {
			methods.put(method.getDeclarationSignature(false), method);
		}

		Type superClass = javaClass.getSuperClass();

		String superClassValue = superClass.getValue();
		
		System.out.println("superClassValue: "+superClassValue);

</string,>

Ant it outputs "java.lang.Object" instead of "BaseModelImpl"

Right now (2015.04.21), "Liferay Plugins" GIT repository is broken, "ant build-service" for sample-service-builder-portlet outputs this:

    [echo] Exception in thread "main" java.lang.NullPointerException
    [echo]     at com.liferay.portal.tools.service.builder.ServiceBuilder._getMethods(ServiceBuilder.java:4490)
    [echo]     at com.liferay.portal.tools.service.builder.ServiceBuilder._getMethods(ServiceBuilder.java:4484)
    [echo]     at com.liferay.portal.tools.service.builder.ServiceBuilder._createModelClp(ServiceBuilder.java:2583)
    [echo]     at com.liferay.portal.tools.service.builder.ServiceBuilder.<init>(ServiceBuilder.java:895)
    [echo]     at com.liferay.portal.tools.service.builder.ServiceBuilder.main(ServiceBuilder.java:305)</init>

It corresponds to the parent class "java.lang.Object" discovery by QDOX. There were almost no changes to this except refactoring.


Do we have JIRA story for this?

Thanks,

I use Java 7 only

[David H Nebinger, módosítva 9 év-val korábban]

As well you should, neither java 6 nor java 8 are supported on the L7 milestones.

[Fuad Efendi, módosítva 9 év-val korábban]

I am talking about current HEAD of "master" branch of both,
https://github.com/liferay/liferay-portal
https://github.com/liferay/liferay-plugins

It is updates daily; there is a bug somewhere which I am trying to fix & or, I would like to know who is going to fix it and how soon.

It is not related to Java version nor Java vendor.


Thanks,

Just try to clone "liferay-plugins" from GIT "master" branch, and run "ant build-service" on sample-service-builder-portlet.

Fortunately, I can use ServiceBuilder from Liferay 7 M4 SDK, but I am not sure that generated code will be forward compatible; plus I want(!!!) to know where the problem is.

Moving to Milestone feedback category. I think this breakage is temporary and will be fixed. The refactoring is still in pretty turbulent waters

[Fuad Efendi, módosítva 9 év-val korábban]

I found that nothing wrong with ServiceBuilder; I run provided sample in isolated environment, and it works. Although it needs references to external portal-service.jar, portal-impl.jar, and util-java.jar

I found that this is a bug with build scripts in Liferay Plugins SDK recently introduced (by refactoring ServiceBuilder). Possibly, build-common-plugin.xml is outdated.

This worked for me (with additional JARs in a classpath):

	<taskdef classpathref="service.builder.classpath" resource="com/liferay/portal/tools/service/builder/ant/taskdefs.properties" />

	<target name="build-service">
		<service-builder apiDir="../tmp/api" hbmFileName="../tmp/src/META-INF/portal-hbm.xml" implDir="../tmp/src" inputFileName="service.xml" modelHintsFileName="../tmp/src/META-INF/portal-model-hints.xml" resourcesDir="../tmp/src" springFileName="../tmp/src/META-INF/portal-spring.xml" sqlDir="../tmp/sql" testDir="../tmp/test/integration" />
	</target>

Plus, there are some outdated Jars which are not needed by ServiceVuilder, but still there.

Work-in-Progress

[Fuad Efendi, módosítva 9 év-val korábban]

I located the problem, this attribute is missing in build-common-plugin.xml:

<attribute name="service.target.entity.name" default="MyService"/>


"MyService" is dummy temporary PoC; I think whole "build-service" macrodef must be rewritten for new ServiceBuilder.

[Fuad Efendi, módosítva 9 év-val korábban]

I was partially wrong; we have "liferay-plugins" repository with updated almost daily com.liferay.portal.tools.service.builder.jar, and we also have outdated "build-service" definition in ANT.

If you want to use newest Service Builder right now, then follow example ANT script from Service Builder source distribution, only subset of available parameters listed here:

<!--?xml version="1.0"?-->


<project>
	<path id="service.builder.classpath">
		<fileset dir="../lib" includes="*.jar" />
		<fileset dir="../../../../tools/sdk/dist" includes="com.liferay.portal.tools.service.builder-*.jar" />
	</path>

	<taskdef classpathref="service.builder.classpath" resource="com/liferay/portal/tools/service/builder/ant/taskdefs.properties" />

	<target name="build-service">
		<service-builder apiDir="../tmp/api" hbmFileName="../tmp/src/META-INF/portal-hbm.xml" implDir="../tmp/src" inputFileName="service.xml" modelHintsFileName="../tmp/src/META-INF/portal-model-hints.xml" resourcesDir="../tmp/src" springFileName="../tmp/src/META-INF/portal-spring.xml" sqlDir="../tmp/sql" testDir="../tmp/test/integration" />
	</target>
</project>
