sapjco3.jar與Maven的命名約定（Springboot）

Question

有問題我想使用springboot java框架編譯集成服務器。我正在使用Maven編譯一個jar文件，但我仍然遇到Maven在存儲庫中存儲jar的問題。

我正在使用的jar是sapjco3.jar，它會在運行時崩潰（不包），因爲它的名字是sapjco3.jar。由於Maven回購命名約定是：

/%groupId%/%artifactId%/%version%/%artifactId%-%version%.jar 

庫最終被稱爲sapjco3-3.0.jar。

是否有某種方法可以在不使用存儲庫的情況下將我的sapjco3.jar彈出到我的應用程序中（我還沒有能夠將它添加到java.library.path中或通過編輯〜/中的條目和xml。 m2目錄）。否則，是否有腳本重新命名它的方式插入後？順便說一句，我的平臺是ubuntu 14.04 LTS。

我的POM文件（缺少XML頭，因爲StackOverflow上不分析是正確的）：

崩潰：

Factory method 'createSapConnection' threw exception; nested exception is java.lang.ExceptionInInitializerError: JCo initialization failed with java.lang.ExceptionInInitializerError: Illegal JCo archive "sapjco3-3.0.jar". It is not allowed to rename or repackage the original archive "sapjco3.jar". 

我只是想這建立！

我解決了這個問題，自定義佈局

import org.springframework.boot.loader.tools.Layouts.Jar; 

public class ResistantToSapjco3JarLayout extends Jar implements CustomLoaderLayout { 

    @Override 
    public void writeLoadedClasses(LoaderClassesWriter writer) throws IOException { 

    // do Spring Boot defaults 
    writer.writeLoaderClasses(); 

    URL jcoClassUrl = getClass().getClassLoader().getResource("com/sap/conn/jco/JCo.class"); 
    if (jcoClassUrl == null) { 
     throw new IllegalStateException("No sapjco3 JAR on plugin classpath. " 
       + "Make sure sapjco3 is added to spring-boot-maven-plugin dependency section"); 
    } 
    if (!jcoClassUrl.toString().startsWith("jar:file")) { 
     throw new IllegalStateException("sapjco3 is not JAR"); 
    } 
    JarURLConnection jarUrlConnection = (JarURLConnection) jcoClassUrl.openConnection(); 
    JarFile sapjco3Jar = jarUrlConnection.getJarFile(); 

    JarWriter jarWriter = (JarWriter) writer; 
    jarWriter.writeNestedLibrary("BOOT-INF/lib/", 
     new Library("sapjco3.jar", new File(sapjco3Jar.getName()), LibraryScope.COMPILE, false)); 

    } 

}
