Alex Harui commented on FLEX-33083: ----------------------------------- I was not able to reproduce the problem with the new zip. I attached swfutils.jar that might be needed to pair with the mxmlc.jar. If that doesn't work, try FlashBuilder again and see if you get the same stack trace in the log. Make sure you clean the project. Then check your location of flex-messaging-common.jar. It needs to be in libs/external/optional. There should be some other jars in there like flex-fontkit.jar. > Flash builder report "An internal build error has occurred. See the error log > for more information." > ----------------------------------------------------------------------------------------------------- > > Key: FLEX-33083 > URL: https://issues.apache.org/jira/browse/FLEX-33083 > Project: Apache Flex > Issue Type: Bug > Components: Project Management > Environment: Flash builder 4.6 , sdk 4.8.0 > Reporter: Alex Harui > Assignee: Alex Harui > Labels: easyfix > Attachments: mxmlc.jar, swfutils.jar, weborb.codegen.test.zip > > > 1. download the source kit from > https://svn.apache.org/repos/asf/incubator/flex/trunk > 2. run ant release > 3. extract apache-flex-sdk-4.8.0-incubating-bin.zip to new folder > 4. extract AIR Integration Kit.zip to folder > 5 copy additional files for Flash Ide ( frameworks/libs\player\* and > frameworks\*-config.xm) > 6.create a simple project with reference to RemoteObject > private var remote:RemoteObject; > remote = new RemoteObject; > flash builder log file : > !ENTRY com.adobe.flexbuilder.project 4 43 2012-06-08 18:27:39.112 > !MESSAGE Uncaught exception in compiler > !STACK 0 > java.lang.NullPointerException > at flex2.compiler.CompilerAPI.getMessagingClasses(CompilerAPI.java:1730) > at flex2.compiler.CompilerAPI.compile(CompilerAPI.java:1538) > at flex2.tools.oem.Application.compile(Application.java:1357) > at flex2.tools.oem.Application.recompile(Application.java:1295) > at flex2.tools.oem.Application.compile(Application.java:894) > at > flex2.tools.flexbuilder.BuilderApplication.compile(BuilderApplication.java:367) > at > com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder$MyBuilder.mybuild(ASApplicationBuilder.java:319) > at > com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder.build(ASApplicationBuilder.java:129) > at > com.adobe.flexbuilder.multisdk.compiler.internal.ASBuilder.build(ASBuilder.java:198) > at > com.adobe.flexbuilder.multisdk.compiler.internal.ASItemBuilder.build(ASItemBuilder.java:70) > at > com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.buildItem(FlexProjectBuilder.java:607) > at > com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.build(FlexProjectBuilder.java:382) > at > com.adobe.flexbuilder.project.compiler.internal.FlexIncrementalBuilder.build(FlexIncrementalBuilder.java:187) > at > org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:728) > at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) > at > org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:199) > at > org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:239) > at > org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:292) > at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) > at > org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:295) > at > org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:351) > at > org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:374) > at > org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:143) > at > org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:241) > at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) -- This message is automatically generated by JIRA.
