[jira] [Created] (MANTRUN-200) Scriptdef tasks fail to load when
running on Java9
Dan Berindei created MANTRUN-200:
------------------------------------
Summary: Scriptdef tasks fail to load when running on Java9
Key: MANTRUN-200
URL: https://issues.apache.org/jira/browse/MANTRUN-200
Project: Maven Antrun Plugin
Issue Type: Bug
Affects Versions: 1.8
Reporter: Dan Berindei
I have a Maven project using maven-antrun-plugin:
{code}
<?xml version='1.0' encoding='UTF-8'?>
<project>
<modelVersion>4.0.0</modelVersion>
<artifactId>my-test-app</artifactId>
<groupId>my-test-group</groupId>
<version>1.0-SNAPSHOT</version>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<id>compile</id>
<phase>compile</phase>
<configuration>
<target>
<ant antfile="build.xml" inheritRefs="true">
<target name="all"/>
</ant>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
{code}
The Ant build file uses a script:
{code}
<?xml version='1.0' encoding='UTF-8'?>
<project name="scriptdef-test-build">
<scriptdef name="test-script" language="javascript">
<![CDATA[
var System = Java.type('java.lang.System');
System.out.println("Working!");
]]>
</scriptdef>
<target name="all">
<test-script/>
</target>
</project>
{code}
On Java 8 it works, but on Java 9 (9-ea+162) it can't find the script engine:

I have attached a debugger and I saw that the {{ScriptEngineManager}} used by {{JavaxScriptRunner}} doesn't have any script engines, because the service loader it uses doesn't find any {{ScriptEngineFactory}} implementations. I have tried {{--add-modules jdk.scripting.nashorn}} and {{--add-opens jdk.scripting.nashorn/jdk.nashorn.api.scripting=ALL-UNNAMED}}, but neither helped.
