When minimising yui with 2.4.6, I get this problem:
java.lang.StringIndexOutOfBoundsException: String index out of range: 232
at java.lang.String.sub
Really, you're having class loader problems in JBoss?
You're going to have to do some kind of exclusion on the competing rhino JAR file. Why is Rhino on the classpath? It may be an optional feature of JBoss you can turn off and avoid the conflict that way.
Workaround: For JBoss AS 7.1.1.Final and YUICompressor 2.4.7
Exclude rhino from dependency:
<dependency>
<groupId>com.yahoo.platform.yui</groupId>
<artifactId>yuicompressor</artifactId>
<version>${yuicompressor.version}</version>
<exclusions>
<exclusion>
<groupId>rhino</groupId>
<artifactId>js</artifactId>
</exclusion>
</exclusions>
</dependency>
Why? See https://github.com/greenlaw110/greenscript/pull/29#issuecomment-4017147
Note: if you have a rhino in classpath by some other way, so seems like you'll get this error again.
I solved this problem by repackaging yuicompressor myself to include most of the rhino source. See my reply to Howard M. Lewis Ship.
The repackaged source can be found here : http://viscri.co.uk/labs/tapestry/yuicompressor-rhino-bugfix-5.0.jar. Just add this to your pom:
<dependency>
<groupId>yuicompressorbugfix</groupId>
<artifactId>yuicompressor-rhino-bugfix</artifactId>
<version>5.0</version>
</dependency>
If you don't run your own version of nexus, you'll have to install it on the machine that you want to build on. This is the command you need I think: http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html
You'll also need to exclude the yuicompressor version that tapestry pulls in:
<dependency>
<groupId>org.apache.tapestry</groupId>
<artifactId>tapestry-yuicompressor</artifactId>
<version>5.3.2</version>
<exclusions>
<exclusion>
<groupId>com.yahoo.platform.yui</groupId>
<artifactId>yuicompressor</artifactId>
</exclusion>
</exclusions>
This should work.
The selected answer's (as of 9/26/2014) jar doesn't exist anymore.
So, I created a fork of yuicompressor where entire rhino package is embedded into the yuicompressor package and namespaced it under yui.
https://github.com/timothykim/yuicompressor
Just clone the repo and run ant
to obtain the jar.
Hope this helps anyone else who stumbles unto this problem.
