Ho installato Maven 3.3.1 e Java 1.7 sul mio computer, Windows 8.1.Ho inserito il comando mvn in Windows, ma la riga di comando restituisce un suggerimento java
MAVEN_HOME=C:\Program Files\Apache\apache-maven-3.3.1
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_75
Path=%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%MAVEN_HOME%\bin;
Ho cercato di accedere a riga di comando mvn, in C: \ Users \ {mionomeutente}>, funziona bene:
C:\Users\{myusername}>java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)
C:\Users\{myusername}>mvn -version

Maven home: C:\Program Files\Apache\apache-maven-3.3.1\bin\..
Java version: 1.7.0_75, vendor: Oracle Corporation

Default locale: en_US, platform encoding: GBK

Ma quando cambio il percorso del comando a D :, un altro disco nella mia macchina, l'uscita diventa:
D:\>mvn --version

D:\>java -version
java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)
Inoltre, quando uso IntelliJ creare il progetto Maven, proprio come quickstart, l'errore di simile è accaduto:
0.123.516,410617 millionsHo provato come mvn -version, mvn -d. Ma continuano a non funzionare. Qualcuno potrebbe aiutarmi? Grazie!!
Aggiornato: Ora le mie variabili d'ambiente è impostata su:
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_75;
CLASSPATH=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;
M2_HOME=C:\Program Files\Apache\apache-maven-3.3.1;
MAVEN_HOME=C:\Program Files\Apache\apache-maven-3.3.1;
PATH=%JAVA_HOME%\bin;%M2_HOME%\bin;{others...}
E il problema esiste ancora.
Aggiornato:
Ogni volta digito dopo il comando mvn in D: percorso, la linea di comando sarà solo tornare java suggerimento; sembra che tutte le cose dopo che sono state ignorate. Proprio come questo:
D:\>mvn fewadsfe

Come si impostano le variabili di ambiente? Inoltre, non inserire il jre nella cartella 'Path =% JAVA_HOME% \ bin;% MAVEN_HOME% \ bin;' –
Sì, ho eliminato la cartella jre per le variabili di ambiente Path. Ma il problema esiste ancora ... – LoGWRiTer
Solo due cose. JAVA_HOME deve essere impostato correttamente, il che significa che Maven deve puntare a un JDK. Solo la cartella bin di 'apache-maven-3.3.1/bin' deve essere nel tuo percorso. Questo è tutto ciò che serve davvero. Successivamente dovresti eseguire 'mvn --version'. Devi chiudere e riaprire la tua console dopo aver modificato le variabili di ambiente. – khmarbaise
