离子cordova构建android：错误：产生EACCES

Question

I've seen many references to changing gradle's execute attribute via chmod, (+x or 755)... None of that seems to make an iota of difference. I still get the message even if I run: sudo ionic cordova build android

I have these settings:

The only thing I could think it would be is due to something in the hooks of a plugin not having execute attributes maybe...

sudo ionic cordova build android

....
> cordova build android

Error: spawn EACCES

[ERROR] An error occurred while running cordova build android (exit code 1).

One of the most annoying things about this error is that it's not giving you enough details and is hiding the root cause of the problem... I've tried adding things like --verbose and --release flags but that changes nothing in terms of resolving issue.

Have got Android Studio 3.0.1

My .profile (based loosely on this ) contains:

export JAVA_HOME=$(/usr/libexec/java_home)
export ANDROID_HOME=~/Library/Android/sdk
#ANDROID_HOME=/opt/android-sdk
export NVM_DIR="$HOME/.nvm"
export PATH=${JAVA_HOME}/bin:${PATH}
export PATH=${ANDROID_HOME}/platform-tools:${PATH}
export PATH=${ANDROID_HOME}/tools:${PATH}
export PATH=${ANDROID_HOME}/tools/bin:${PATH}
#${ANDROID_HOME}/tools/bin:${HOME}/bin:.
export GRADLE_HOME="/Applications/Android Studio.app/Contents/gradle/gradle-4.1"
export PATH=${PATH}:${GRADLE_HOME}/bin

This is my only other thought at this point.. a space in Android Studio. That may be messing with paths, so I'm inclined to copy that out.

which gradle yields a correct path though...

/Applications/Android Studio.app/Contents/gradle/gradle-4.1/bin/gradle

(earlier there had been an old brew version that I uninstalled, but pointing to the Android Studio version with path seems to have made no difference).

One final footnote... Back in the day when android was a command that could be used for both sdk and apk manager functionality too, you used to have to do something like accept license terms or something of that nature. There's nothing like that I'm missing like that here too is there? Only, I'm scratching my heading for options.

After SurajRao's tips, running cordova build android --verbose ,

I am now getting past initial problems.

This was done by doing this:

cd <project folder>/platform/android/
chmod +x build.gradle 
chmod +x gradlew

It now yields:

Error: /opt/IonicProjects/aews_official_rc_1.2.09/platforms/android/gradlew: Command failed with exit code 1 Error output:
FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':CordovaLib'.
> Could not resolve all files for configuration ':CordovaLib:classpath'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug optionto get more log output.

* Get more help at https://help.gradle.org

Will try gradle init per suggestion here ... And that seemed to fix it.

Answer 1

I find using --verbose flag with cordova command directly instead of ionic command gives debug information in cordova's build process.

 cordova build android --verbose

EDIT -> I raised a Github request with Ionic here regarding verbose and it is supposed to be fixed for Ionic Cli 4.

According to your logs,

Running command: /opt/IonicProjects/aews_official_rc_1.2.09/platforms/android/gradlew cdvBuildDebug -b /opt/IonicProjects/aews_official_rc_1.2.09/platforms/android/build.gradle -Dorg.gradle.daemon=true -Dorg.gradle.jvmargs=-Xmx2048m -Pandroid.useDeprecatedNdk=true

is your problem.

You will have to give executable permissions to

/opt/IonicProjects/aews_official_rc_1.2.09/platforms/android/build.gradle

and

/opt/IonicProjects/aews_official_rc_1.2.09/platforms/android/gradlew 

using chmod +x

Answer 2

If you are using Ubuntu then you need to add sudo cordova build android --verbose in your terminal. It is basically a permission issue.
