Title: fix too long classpaths in script(bat/bash).

the maximum length of the string that you can use at the command prompt is 8191 characters. http://support.microsoft.com/kb/830473/en-us

Create manifest.jar it contains Class-Path manifest.
java classpath option need only a manifest.jar.

```
java -Xjvmopt1 -Xjvmopt2 -cp org.name-version-artifactClassifier.jar:scala-liblary.jar:aaaaaa.jar:bbbbbb:jar:cccc.jar:......:xxxxxx.jar mainClass arg1 arg2
```
↓
```
java -Xjvmopt1 -Xjvmopt2 -cp org.name-version-artifactClassifier-manifest.jar mainClass arg1 arg2
```

This patch affects both the batch script and bash script.
