when I'm using mvn install, and found that the number of compiling sources is different from that built from eclipse project build.
that is when compiled from mvn there's info message telling
[INFO] Compiling 359 source files to E:\workspace\project\target\classes
but when using eclipse-> project -> build project, there's over 400 classes, that means some classes are not compiled when using maven.
Is there anyone ever met similar problem?
ps: the tried with JDK 1.7, JDK1.8 and maven 3.2.1, 3.3, 3.1.1 and meet the same problem.

As shown in the picture, when I build scala project with sbteclipse and import to eclipse, when changing build.sbt , jars are downloaded to my computer but not to scalaProject. I do not know why. Can someone help me?
scala version: 2.11.8
sbt version: 0.13.15
stbeclipse:5.1.0
I assume that you're using the Scala IDE plugin for Eclipse, correct?
The sbteclipse SBT plugin merely provides a command to generate an Eclipse Scala project from the SBT build. Before using Eclipse, you're supposed to issue the following command (from the command line) to SBT:
sbt eclipse
This should generate the project files for your Eclipse project. After executing this command, you can open your project using Eclipse (with the Scala IDE plugin).
Note that, at present, the Scala IDE Eclipse plugin does not support SBT build files. That is, if you change your SBT build file, then Eclipse will be none the wiser, until you re-run the above command.
You might want to consider switching to IntelliJ IDEA (instead of Eclipse) which has a full-featured Scala plugin that fully supports SBT builds, including downloading any dependencies. For my money (both IDEs are free) IntelliJ is light-years ahead of Eclipse for Scala development.
I'm using a maven plugin in my POM file. When I build the project, I get an error:
`[ERROR] Failed to execute goal br.com.ingenieux:jbake-maven-plugin:0.0.9:generate (default-cli) on project uts-documentation: The plugin br.com.ingenieux:jbake-maven-plugin:0.0.9 requires Maven version 3.1.1 -> [Help 1]`
My embedded maven version is 3.0.4. How can I update to the required version without installing a separate instance of maven (would like to avoid that if possible)?
Upgrading to a more recent Eclipse version will bring an updated embedded version of Maven. For example the Eclipse Luna installation that I am running has Maven 3.2.1 embedded.
I'm trying to build the project of hadoop. I followed the official document as follows on how to do that.
http://wiki.apache.org/hadoop/HowToContribute
https://wiki.apache.org/hadoop/EclipseEnvironment
I've git clone the project, maven install it successfully, but when I import the project, or even a sub-project like 'hadoop-yarn-api', I got the following errors on maven:
Description Resource Path Location Type
Plugin execution not covered by lifecycle configuration: org.apache.hadoop:hadoop-maven-plugins:3.0.0-SNAPSHOT:protoc (execution: compile-protoc, phase: generate-sources) pom.xml /hadoop-yarn-api line 73 Maven Project Build Lifecycle Mapping Problem
Then I'm trying to mvn clean install the project via External Tools Configuration in eclipse, it also failed on:
[ERROR] Failed to execute goal org.apache.hadoop:hadoop-maven-plugins:3.0.0-SNAPSHOT:protoc (compile-protoc) on project hadoop-yarn-api: org.apache.maven.plugin.MojoExecutionException: 'protoc --version' did not return a version -> [Help 1]
But the curious part is that when I cd into the root directory of 'hadoop-yarn-api' and invoke mvn clean install, it can be built successfully.
I'm using m2ecipse in eclipse, and I'm sure that I've changed to the maven which is exactly the one that I'm used in command line, not the embedded one.
And I've installed protocol buffers 2.5.0:
$ protoc --version
libprotoc 2.5.0
Could anyone give me some idea? Many thanks!
P.S.

Trying to find the ScalaTest plugin for use with Eclipse Luna and Scala IDE for Eclipse 4.0.0 (aka Lithium). Currently using Milestone 2 of the Scala IDE for Eclipse Lithium plugin.
The ScalaTest plugin used to be part of the Scala IDE for Eclipse plugin (appeared on the list and you could check the box it to install--Scala IDE for Eclipse is supposed to be an ecosystem of plugins, ScalaTest being one of them). It doesn't appear to be there any more.
It's not on the list,
When I check "Installation Details" it doesn't appear either, and
Test configurations don't appear under "Run As..."
But there is mention of Luna in the ScalaTest plugin Github site for the scalatest plugin (https://github.com/scalatest/scalatest-eclipse-plugin), which is supposed to be part of the Scala IDE for Eclipse ecosystem.
The tests run fine from the SBT command line. So I know the ScalaTest jar file is in the classpath and is of a compatible version for my project. The ScalaTest jar file appears as an external jar file in my project in Eclipse, and the tests compile in Eclipse. Other Scala IDE for Eclipse functions seem to work correctly.
System Configuration:
Eclipse Version: Luna (4.4.0),
Scala IDE for Eclipse Version: Lithium 4.0.0 Milestone 2, for Luna and Scala 2.11.1 (download site http://download.scala-ide.org/sdk/lithium/e44/scala211/dev/site)
Java Version: Java 1.8_05,
Scala Version: 2.11.1,
Build Tool: SBT 0.13.5, running under Java 1.8_05,
ScalaTest Version: scalatest_2.11-2.2.0.jar (copied into the lib directory of my project)
My Eclipse project file is generated by SBT using the eclipse SBT command, and loaded into Eclipse using the standard "Import->Existing Projects Into Workspace..." method. The build.sbt file is a single line reading scalaVersion := "2.11.1".
Is there a ScalaTest plugin for Eclipse Luna and Scala IDE for Eclipse 4.0 (Lithium)? If so, where do I go about finding it?
This is a version of the Scala IDE that works with Eclipse Luna (version 4.4).

I used to add "generate-resources" to Maven's "Goals to run on project import" setting in older m2e.
Now I have new version of eclispe and m2e, and the setting is gone.
How can I add the generated-sources o the eclipse project automatically?
see this older question:
Problems by import of a multiple modules maven 2 project into eclipse workspace
I am using m2e 1.0.200.20111228-1245,
Eclipse version is as follows
Version: Indigo Service Release 2
Build id: 20120216-1857
Maven is: 3.0.4 (r1232337; 2012-01-17 09:44:56+0100)
Pls. note that this is a centrally managed system, I have no root access etc.
