scriptengine-powershell

PowerShell script engine for Java implementing JSR 223

Requirements

• .NET 4
• Windows Management Framework 3.0

Usage

Simply add the JAR and DLLs to your classpath and follow the Java Scripting Programmer's guide

Build

Run gradlew script, it produces JARs and DDLs in build/install

How it works

It uses jni4net to call the PowerShell API.

Bindings

Script bindings are exported in the PowerShell engine before running the script.

PowerShell supported types are: string, char, byte, int, long, bool, double, array, hashtable.

Java List are mapped to PowerShell array. Java Map are mapped to PowerShell hashtable.

The following types are NOT supported: single decimal datetime xml.

To pass arguments/parameters to a PowerShell ($args), you can set a binding called args.

Script Result

Results produced by return or Write-Output are retrieved and converted back to Java.

To update jni4net bindings

• Look at the utils.proxygen.xml file. It defines what proxies will be generated.
• Run generateProxies.cmd, it will generate
  • Java proxies of .NET classes
  • and C# codebe-hind classes
• Now you need to compile codebe-hind classes into assembly.
  • Start Visual Studio,
  • open utils.csproj
  • eventually add newly generated files to the project
  • compile it
