Hi, manage to create a workaround for yarn3 using a custom plugin, till #612 First in [build.environment]
NODE_VERSION = "16"
NPM_FLAGS = "--version"
[[plugins]]
package = "/.netlify/netlify-plugin-yarn"then create
manifest.yml is just name: netlify-plugin-yarn
inputs: []and index.js is responsible for moving cache folder, setting module.exports = {
onPreBuild: async ({ utils: { build, run } }) => {
const cacheDir = '.yarn_cache'
process.env['YARN_CACHE_FOLDER'] = `${process.env.HOME}/${cacheDir}`
process.env['NETLIFY_CACHE_DIR'] = `${process.env.NETLIFY_BUILD_BASE}/cache`
try {
await run.command(`mv ${process.env.NETLIFY_CACHE_DIR}/${cacheDir} ${process.env.YARN_CACHE_FOLDER}`)
} catch (error) {
console.log('No yarn cache found')
}
try {
await run.command('corepack enable')
} catch (error) {
return build.failBuild(error)
}
},
}package.json {

3.0.1) and yarn is not cached at all, it takes1m 54sin best cases and3m 17sin worst cases, including the cache restore phase.On the contrary, on GitHub actions with the yarn cache action, the Fetch phase is completely skipped, and it just runs the linking phase. It takes ~20 seconds.
I pasted the logs at the end of the issue, the relevant part are these:
