maven：mvn清潔程序包拋出錯誤“輸入的格式不是XZ。 ”

Question

在做MVN清潔包

我收到以下錯誤：

    [ERROR] Failed to resolve target definition C:\Users\xyz\git\sql-converter sql.target.target: 

Failed to load p2 metadata repository from location download.eclipse.org/releases/neon: 

Unable to read repository at http://download
    .eclipse.org/releases/neon. 

Unable to read repository at http://download.eclipse.org/releases/neon/201606221000. 

Input is not in the XZ format -> [Help 1]
    [ERROR]
    [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
    [ERROR] Re-run Maven using the -X switch to enable full debug logging.
    [ERROR]
    [ERROR] For more information about the errors and possible solutions, please read the following articles:
    [ERROR] [Help 1] 

誰能給我照個照 我找不到與錯誤有關的任何內容：“ 輸入的格式不是XZ。 ”

有關更多詳細信息，當我訪問站點releases / neon / 201703231000 / artifacts.xml.xz時 ，出現以下錯誤消息：

XML Parsing Error: not well-formed
Location: http://download.eclipse.org/releases/neon/201703231000/artifacts.xml.xz
Line Number 1, Column 1:7zXZ

• 您認為這很正常嗎？ 對於其他文件，例如releases / neon / 201703231000 / content.xml.xz ，可以下載。 它們都是XZ格式。
• 該消息是否表示生成文件時發生了錯誤？

Answer 1

訪問http://download.eclipse.org/releases/neon/201606221000時出現問題，這導致輸入的格式不是xz格式錯誤。 我只是將更新站點更改為以下任一站點：

http://download.eclipse.org/releases/neon/201606221000/
    http://download.eclipse.org/releases/neon/201609281000/
    http://download.eclipse.org/releases/neon/201610111000/
    http://download.eclipse.org/releases/neon/201612211000/
    http://download.eclipse.org/e4/snapshots/org.eclipse.e4.tools/latest/

問題就解決了。

在我們的問題中，我們使用帶有tycho插件的maven來構建eclipse rcp應用程序。 我們使用的tycho版本是0.24.0 。

在運行maven clean install -X我的堆棧如下：

這意味着我們在org.tukaani.xz上遇到了一些問題。 然后，我將其與使用tycho版本1.0.0的另一版本進行了比較 ，發現使用該版本的tycho依賴於org.apache.commons：commons-compress：jar：1.9：compile，而這個不再依賴於org.tukaani： xz：jar：1.4：compile 。 因此，我將tycho版本更新為1.0.0，並且該版本正在運行。

因此，一種解決方案可能是：如果您的Maven構建使用tycho，請檢查pom.xml中的tycho版本，如果它是0.24.0或低於1.0.0，則應考慮將其升級到1.0.0。
