Product: Ant
Version: 1.10.14
Hardware: PC
Status: NEW
Severity: normal

Could you please explain, how to use
<script language="javascript" ...
with Java 17.
Under the https://ant.apache.org/manual/Tasks/script.html there's only
information about using external dependencies.
Found one useful link -

Seems like adding libs to %ANT%/lib helps but it's not the solution in our case
as we need to run ant with both Java 8 and 17.
Adding
<path id="javax.classpath">
<pathelement location="./nashorn-core-15.4.jar"/>
<pathelement location="./asm-9.6.jar"/>
<pathelement location="./asm-util-9.6.jar"/>
</path>
or
<path id="javax.classpath">
<pathelement location="./graal-sdk-22.3.1.jar"/>
<pathelement location="./icu4j-72.1.jar"/>
<pathelement location="./js-22.3.1.jar"/>
<pathelement location="./js-launcher-22.3.1.jar"/>
<pathelement location="./regex-22.3.1.jar"/>
<pathelement location="./truffle-api-22.3.1.jar"/>
</path>
and running
<script language="javascript" manager="javax"
classpathref="javax.classpath">
...
Still generates
Java 15 has removed Nashorn, you must provide an engine for running JavaScript
yourself. GraalVM JavaScript currently is the preferred option.
