[EAGLE-881] Url of scala-tools repository is no longer valid

[DadanielZ]

Removed the repositories declaration of "Scala-Tools Maven2 Repository" from "eagle-parent" pom file, so that maven can download them from default maven repo.

[DadanielZ]

Build failed because Jenkins is using jdk1.8 but not jdk1.7:

[ERROR] error: error while loading CharSequence, class file '/usr/local/asfpackages/java/jdk1.8.0_102/jre/lib/rt.jar(java/lang/CharSequence.class)' is broken

[haoch]

@DadanielZ eagle currently requires jdk-1.8 to compile, why the build failed?

[DadanielZ]

@haoch this is for branch-0.4, which should be using jdk 1.7 to build.

[haoch]

@DadanielZ is this PR still valid?

[DadanielZ]

@haoch Yes it is still valid. jenkin server is using jdk1.8 but not jdk1.7 to build branch-0.4, which lead to the failure.

[haoch]

OK, please move on to merge the PR directly.

[DadanielZ]

merged, hence closing the PR
