.SYNOPSIS
Apache Ignite.NET build script.

.DESCRIPTION
Builds all parts of Apache Ignite.NET: Java, .NET, NuGet. Copies results to 'bin' and 'nupkg' folders.

Requirements:
* PowerShell 3
* JDK 8+
* MAVEN_HOME environment variable or mvn.bat in PATH

.PARAMETER skipJava
Skip Java build.

.PARAMETER skipDotNet
Skip .NET build.

.PARAMETER skipDotNetCore
Skip .NET Core build.

.PARAMETER skipNuGet
Skip NuGet packaging.

.PARAMETER skipCodeAnalysis
Skip code analysis.

.PARAMETER clean
Perform a clean rebuild.

.PARAMETER platform
Build platform ("Any CPU", "x86", "x64").

.PARAMETER configuration
Build configuration ("Release", "Debug").

.PARAMETER mavenOpts
Custom Maven options, default is "-U -P-lgpl,-scala,-examples,-test,-benchmarks -Dmaven.javadoc.skip=true".

.PARAMETER jarDirs
Java jar files source folders, default is "modules\indexing\target,modules\core\target,modules\spring\target"

.PARAMETER asmDirs
.NET assembly directories to copy pre-build binaries from. Default is "", which means no copy.

.PARAMETER nugetPath
Path to nuget.exe.

.PARAMETER version
NuGet version override (normally inferred from assembly version).

.EXAMPLE
.\build.ps1 -clean  
# Full rebuild of Java, .NET and NuGet packages.

.EXAMPLE
.\build.ps1 -skipJava -skipCodeAnalysis -skipNuGet -configuration Debug -platform x64
# Quick build of .NET code only.
