"error TS5056 overwritten by multiple input files" found after upgraded loopback core to 1.10.6 and typescript to 3.7.2

1. upgraded loopback as below:

   "dependencies": {
-    "@loopback/boot": "^1.5.10",
-    "@loopback/context": "^1.23.4",
-    "@loopback/core": "^1.10.6",
-    "@loopback/openapi-v3": "^1.10.0",
-    "@loopback/repository": "^1.15.3",
-    "@loopback/rest": "^1.22.0",
-    "@loopback/rest-explorer": "^1.4.3",
-    "@loopback/service-proxy": "^1.3.10",
+    "@loopback/boot": "^1.5.11",
+    "@loopback/context": "^1.23.5",
+    "@loopback/core": "^1.10.7",
+    "@loopback/openapi-v3": "^1.10.1",
+    "@loopback/repository": "^1.15.4",
+    "@loopback/rest": "^1.23.0",
+    "@loopback/rest-explorer": "^1.4.4",
+    "@loopback/service-proxy": "^1.3.11",
   },
   "devDependencies": {
-    "@loopback/build": "^2.0.15",
-    "@loopback/eslint-config": "^4.1.3",
-    "@loopback/testlab": "^1.9.3",
+    "@loopback/build": "^2.0.16",
+    "@loopback/eslint-config": "^4.1.4",
+    "@loopback/testlab": "^1.9.4",
-    "typescript": "~3.6.4"
+    "typescript": "~3.7.2"
   }

I clean and rebuild the project, got the below error:

error TS5056: Cannot write file '/home/wayahead/workspace/loopback/pinwheel/besim/dist/datasources/client.datasource.d.ts' because it would be overwritten by multiple input files.

2. if I roll typescript back 3.6.4, then there is no error. but if checked into @loopback/build/package.json, typescript 3.7.2 is found.

The project and client.datasource.ts was generated by previous version of loopback.

So how to solve this issue caused by loopback upgrading?

Either stick with typescript@~3.6.4 or rename <name>.datasource.json to <name>.datasource.config.json. The latest version of @loopback/cli (1.25.0) already generates datasources with the new convention to deal with microsoft/TypeScript#34761.
