-----------------------------------
Summary: Update the closure compiler for better support of modern
JavaScript
Key: TAP5-2777
URL: https://issues.apache.org/jira/browse/TAP5-2777
Project: Tapestry 5
Issue Type: Task
Components: tapestry-webresources
Affects Versions: 5.8.6
Reporter: Chris Poulsen
A couple of years ago we encountered errors related to the closure compiler not
understanding certain modern JavaScript constructs.
The details are sort of hazy, but IIRC the newest version(s) of the compiler
were not just drop-in upgrades (primo 2022). We ended up with "v20210505" back
then, it allowed our JavaScript to pass through and was still just a drop-in
upgrade.
We have been running the following config in production for 2 years (on a bunch
of installations) without issues, so maybe more people would benefit from this
upgrade.
{code:java}
runtimeOnly("org.apache.tapestry:tapestry-webresources:$tapestryVersion") {
exclude group: 'com.google.javascript'
}
runtimeOnly("com.google.javascript:closure-compiler-unshaded:v20210505")
runtimeOnly("com.google.javascript:closure-compiler-externs:v20210505")
{code}
Ideally the compiler support would be updated to the newest version and kept
up-to-date, but for a low hanging fruit, this one should be a simple step.
