DevEco Studio软件创建工程后需要修改两个地方：

修改第二个build-profile.json5文件

将原先内容：

{
  "app": {
    "signingConfigs": [],
    "products": [
      {
        "name": "default",
        "signingConfig": "default",
        "compatibleSdkVersion": "4.1.0(11)",
        "runtimeOS": "HarmonyOS",
        "buildOption": {
          "strictMode": {
            "caseSensitiveCheck": true,
          }
        }
      }
    ],
    "buildModeSet": [
      {
        "name": "debug",
      },
      {
        "name": "release"
      }
    ]
  },
  "modules": [
    {
      "name": "entry",
      "srcPath": "./entry",
      "targets": [
        {
          "name": "default",
          "applyToProducts": [
            "default"
          ]
        }
      ]
    }
  ]
}

改为

{
  "app": {
    "signingConfigs": [],
    "products": [
      {
        "name": "default",
        "signingConfig": "default",
        "compileSdkVersion": 11,
        "compatibleSdkVersion": 11,
        "runtimeOS": "OpenHarmony",
        "buildOption": {
          "strictMode": {
            "caseSensitiveCheck": true,
          }
        }
      }
    ],
    "buildModeSet": [
      {
        "name": "debug",
      },
      {
        "name": "release"
      }
    ]
  },
  "modules": [
    {
      "name": "entry",
      "srcPath": "./entry",
      "targets": [
        {
          "name": "default",
          "applyToProducts": [
            "default"
          ]
        }
      ]
    }
  ]
}

在修改第一个entry\build-profile.json5文件，根据自己的工程选择abiFilters

{
  "apiType": "stageMode",
  "buildOption": {
    "externalNativeOptions": {
      "path": "./src/main/cpp/CMakeLists.txt",
      "arguments": "",
      "cppFlags": "",
//      HarmonyOS工程
//      "abiFilters": ["arm64-v8a", "x86_64"]
//      OpenHarmony工程
      "abiFilters": ["arm64-v8a", "x86_64", "armeabi-v7a"]
    }
  },
  "buildOptionSet": [
    {
      "name": "release",
      "arkOptions": {
        "obfuscation": {
          "ruleOptions": {
            "enable": false,
            "files": [
              "./obfuscation-rules.txt"
            ]
          }
        }
      },
      "nativeLib": {
        "debugSymbol": {
          "strip": true,
          "exclude": []
        }
      }
    },
  ],
  "targets": [
    {
      "name": "default"
    },
    {
      "name": "ohosTest",
    }
  ]
}

修改后需要重启工程。
