Angular fileReplacements doesn't replace files if they occur in assets.
This code doesn't work in Angular 9 but works in version 8:
"assets": [
"src/web.config"
]
...
"fileReplacements": [
{
"replace": "src/web.config",
"with": "src/configs/web.stage.config"
}
]
How can it be fixed?
You should copy assets using the assets property instead of file replacements.
This is a simplification of my angular.json file, showing only the relevant properties under configurations.
{
"projects": {
"my-project": {
"architect": {
"build": {
"configurations": {
"staging": {
"assets": [
{ "glob": "**/*", "input": "src/assets/", "output": "/assets/" },
{ "glob": "web.config", "input": "src/environments/staging/", "output": "/" }
],
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.staging.ts"
}
]
},
"production": {
"assets": [
{ "glob": "**/*", "input": "src/assets/", "output": "/assets/" },
{ "glob": "web.config", "input": "src/environments/prod/", "output": "/" }
],
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}
]
}
}
}
}
}
}
}
I had the same problem on angular 9 and downgrading "@angular-devkit/build-angular" from version ^0.1000.3 to ^0.900.7 did the trick
