When node is not installed, rhino engine throws NoSuchMethodError #82

Open wsargent opened 7 years ago

This is an example of https://github.com/sbt/sbt-js-engine/issues/56, where an old version of Rhino seems to be causing errors:

The note in https://github.com/ksoichiro/gradle-web-resource-plugin/blob/master/build.gradle#L51 seems to explain why:

// java.lang.NoSuchMethodError: org.mozilla.javascript.ScriptRuntime.setObjectProp
--
  | // Gradle distribution has an older Rhino (1.7R3) and causing conflict.
  | // In 1.7R3, ScriptRuntime does not have setObjectProp() method, which causes the above error.

So the solution should be to update Rhino. I'm not sure how/why an outdated Rhino would be loaded, but that's another question.

The workaround is to install an up-to-date node.js from https://nodejs.org/en/download/package-manager/

@wsargent I am just wondering why we had this problem with play 2.6.1 version. With the M- releases we had no problems with this? Are there any changes in the play framework related to this problem? Best wishes, Btw: Thank you for your excellent work!!! Freshwood

The updated sbt-web plugins happened fairly late in the process. It's probably connected to https://github.com/playframework/playframework/issues/7045
