android studio rootproject,Android Studio 0.4.3 - Task 'assemble' not found in root project | 易学教程...

Updated to 0.4.3 the other day and trying to start a new project, not even use an existing project, and I get this error: FAILURE: Build failed with an exception. What went wrong: Task 'assemble' not found in root project 'XXX'.

Try: Run gradle tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Here's what I found in the log file: 2014-01-26 09:50:18,186 [ 276355] WARN - nal.AbstractExternalSystemTask - com.android.builder.model.SourceProvider.getAidlDirectories()Ljava/util/Collection; com.intellij.openapi.externalSystem.model.ExternalSystemException: com.android.builder.model.SourceProvider.getAidlDirectories()Ljava/util/Collection; at org.jetbrains.plugins.gradle.service.project.GradleExecutionHelper.execute(GradleExecutionHelper.java:185) at org.jetbrains.plugins.gradle.service.project.GradleProjectResolver.resolveProjectInfo(GradleProjectResolver.java:113) at org.jetbrains.plugins.gradle.service.project.GradleProjectResolver.resolveProjectInfo(GradleProjectResolver.java:61) at com.intellij.openapi.externalSystem.service.remote.RemoteExternalSystemProjectResolverImpl$1.produce(RemoteExternalSystemProjectResolverImpl.java:41) at com.intellij.openapi.externalSystem.service.remote.RemoteExternalSystemProjectResolverImpl$1.produce(RemoteExternalSystemProjectResolverImpl.java:37) at com.intellij.openapi.externalSystem.service.remote.AbstractRemoteExternalSystemService.execute(AbstractRemoteExternalSystemService.java:59) at com.intellij.openapi.externalSystem.service.remote.RemoteExternalSystemProjectResolverImpl.resolveProjectInfo(RemoteExternalSystemProjectResolverImpl.java:37) at com.intellij.openapi.externalSystem.service.remote.wrapper.ExternalSystemProjectResolverWrapper.resolveProjectInfo(ExternalSystemProjectResolverWrapper.java:49) at com.intellij.openapi.externalSystem.service.internal.ExternalSystemResolveProjectTask.doExecute(ExternalSystemResolveProjectTask.java:48) at com.intellij.openapi.externalSystem.service.internal.AbstractExternalSystemTask.execute(AbstractExternalSystemTask.java:137) at com.intellij.openapi.externalSystem.service.internal.AbstractExternalSystemTask.execute(AbstractExternalSystemTask.java:123) at com.intellij.openapi.externalSystem.util.ExternalSystemUtil$3.execute(ExternalSystemUtil.java:471) at com.intellij.openapi.externalSystem.util.ExternalSystemUtil$4$2.run(ExternalSystemUtil.java:549) at com.intellij.openapi.progress.impl.ProgressManagerImpl$TaskRunnable.run(ProgressManagerImpl.java:464) at com.intellij.openapi.progress.impl.ProgressManagerImpl$2.run(ProgressManagerImpl.java:178) at com.intellij.openapi.progress.ProgressManager.executeProcessUnderProgress(ProgressManager.java:209) at com.intellij.openapi.progress.impl.ProgressManagerImpl.executeProcessUnderProgress(ProgressManagerImpl.java:212) at com.intellij.openapi.progress.impl.ProgressManagerImpl.runProcess(ProgressManagerImpl.java:171) at com.intellij.openapi.progress.impl.ProgressManagerImpl$8.run(ProgressManagerImpl.java:373) at com.intellij.openapi.application.impl.ApplicationImpl$8.run(ApplicationImpl.java:420) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) at com.intellij.openapi.application.impl.ApplicationImpl$1$1.run(ApplicationImpl.java:150)

And here's my build.gradle file (untouched): // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.8.+' } } allprojects { repositories { mavenCentral() } }

I've checked out a few posts online, but none have worked so far. Any help would be appreciated.
