maven-release-plugin是否與Java 9兼容？

Question

我只是試圖用maven-release-plugin發佈我的Java 9兼容項目。然而，它沒有在maven-compiler-plugin與

未能執行目標 org.apache.maven.plugins：Maven的編譯器插件：3.7.0：編譯 （默認編譯）項目電子郵件：致命錯誤編譯：無效 目標版本：9

有趣的是maven-compiler-plugin工作的情況下，罰款我運行它獨立。 我的設置：

 <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-compiler-plugin</artifactId> 
      <version>3.7.0</version> 
      <configuration> 
       <source>9</source> 
       <target>9</target> 
      </configuration> 
     </plugin> 

     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-release-plugin</artifactId> 
      <version>2.5.3</version> 
      <configuration> 
       <autoVersionSubmodules>true</autoVersionSubmodules> 
       <tagNameFormat>v@{project.version}</tagNameFormat> 
      </configuration> 
     </plugin> 

Maven version 3.5.0。

mvn clean install工作正常;

mvn release:prepare release:perform -DignoreSnapshots=true由於上述例外而失敗。

調試輸出：

Answer 1

按照Java+9+-+Jigsaw它被更新最近沒有在maven-release-plugin爲與JDK9兼容需要或期望改變。

此外，在問題中共享的日誌中，您的案例中的輸出似乎是由於配置錯誤的Maven與Java版本小於9。

---

當我面臨着類似的問題，我已經注意到，使用sudo執行，通常在命令提示符下是不同的，當使用Maven的Java版本。

---

要堅持以行家用java的版本一致確保您有配置mavenrc。你可以做，以類似的方式，以這樣的：

vi ~/.mavenrc 

，然後用內容保存如下：

export PATH 
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home 
export PATH=${PATH}:$JAVA_HOME/bin 

---

執行

mvn -version 

，並確保其輸出通過命令提示符和智能終端是一致的。

Answer 2

==========如果您使用Heroku的===========

轉到system.properties並設置：

java.runtime.version=9 

而且將以下內容添加到pom中。xml for maven：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>3.6.2</version> 
    <configuration> 
     <source>9</source> 
     <target>9</target> 
    </configuration> 
</plugin> 

檢查this out。
