Maven（命令行）：此环境不提供编译器

Question

Failed to execute goal or.apache.maven.plugins:maven-compiler-plugin:3.1:comple <default-compile> on project google-play-services: Compilation failure

No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

This is the result when using the Android SDK Deployer from the commandline in Windows. I added JAVA_HOME C:\\Program Files (x86)\\Java\\jdk1.7.0_45 to my system variables.

Did I configured the wrong parts?

Answer 1

This error can also happen if you install a new version of JAVA (JRE), because the Java installer change the order of environment variables on Windows.

So, verify the PATH values in the System Variables . If you see the:

C:\Program Files (x86)\Common Files\Oracle\Java\javapath

Or:

C:\ProgramData\Oracle\Java\javapath

On the top of the list, edit the PATH and change the order of the previous paths to stay below to the JDK path variable (per example, C:\\Program Files\\Java\\jdk1.8.0_162\\bin ).

Answer 2

Normally this happens, compilation of the source cannot be done from JRE(Runtime Environment) its for running the compiled code.

So first thing should done is validating JAVA_HOME path defined in environment variables.

it should be directed to JDK. eg:

C:\\Program Files (x86)\\Java\\jdk1.8.0_111

Answer 3

The problem was very easy to solve. I only had to restart the commandline after changing the system variables.

Answer 4

While setting JAVA_HOME on windows os use Progra~1 instead of Program files since it has space in between eg C:\\Progra~1\\Java\\jdk1.8.0_251

Progra~1 = 'Program Files' Progra~2 = 'Program Files(x86)'

Answer 5

I run my spring boot project in vscode, I stumbled on this same issue. Adding this to my pom solved it

<plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <fork>true</fork>
                <executable>C:\Program Files\Java\jdk-13.0.2\bin\javac.exe</executable>
            </configuration>
        </plugin>
