如何将Java11（Java10）与Eclipse插件一起使用？ [英] How to use Java11 (Java10) with Eclipse Plugin?

问题描述

如果我在Eclipse插件中将JavaSE-10指定为最低执行环境：

将我的插件作为Eclipse应用程序启动时出现以下错误：

  org.osgi.framework.BundleException：无法解析模块：org.treez.core [597] 
未解决的要求：要求-功能：osgi.ee； filter：=（&（osgi.ee = JavaSE）（version = 10）） 
未解决的要求：Require-Bundle：org.treez.javafxd3;可见性：= reexport 
-> Bundle-SymbolicName：org.treez.javafxd3; bundle-version = 1.0.0.qualifier; singleton：= true 
 org.treez.javafxd3 [586]

我检查了

• Java10是reverenc


• 10被选择为合规级别

我使用Oxygen.3a版本（4.7.3a）内部版本号：20180405-1200

=>这是蚀春分的错误吗？

=>我还能检查什么来解决此问题？

如果我从最低执行环境设置中删除JavaSE-10，则可以启动Eclipse应用程序，并且插件似乎可以正常工作。

导出时我收到以下警告的插件：

 ＃25.04.18，12:25:40 MESZ 
＃Eclipse编译器Java（TM）v20180330-0919，3.13.12，版权所有IBM Corp 2000，2015。保留所有权利。 
选项-bootclasspath在法规遵从性级别9及更高级别不支持
  

当我尝试使用从更新页面安装插件后，我得到ClassNotFoundException：

  ...

如果我使用Java8一切正常。

  我使用了Java 11.0.1和Eclipse SimRel 2018-09（加上Java11支持插件）

  
  

  If I specify JavaSE-10 as minimum execution environment in my Eclipse plugin:

  I get following errors when starting my plugin as Eclipse Application:

  org.osgi.framework.BundleException: Could not resolve module: org.treez.core [597]
    Unresolved requirement: Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=10))"

  I checked that

  • Java10 is reverenced under Installed JREs
  • 10 is selected as compliance level

  I use Oxygen.3a Release (4.7.3a) Build id: 20180405-1200

  =>Is this a bug in eclipse equinox?

  =>What else can I check to resolve this issue?

  If I remove JavaSE-10 from the minimum execution environment settings I am able to start the Eclipse Application and the plugin seems to work fine.

  When I export the plugin I get following warning:

  # 25.04.18, 12:25:40 MESZ
  # Eclipse Compiler for Java(TM) v20180330-0919, 3.13.102, Copyright IBM Corp 2000, 2015. All rights reserved.
  option -bootclasspath not supported at compliance level 9 and above
  

  When I try to use the plugin after installing it from my update page, I get a ClassNotFoundException:

  ...

  If I use Java8 everything works fine.

  • How to set up java 10 in Eclipse Oxygen?

  • How to add org.eclipse.swt (and other plugin dependencies) as an automatic Java9 module?

  解决方案

  What worked for me as a work around was to

  • Remove the required version entries from the manifest files and ignore the corresponding warnings

  • Activate the option "Use class files compiled in the workspace" in the export wizard:

  (Therefore I assume that something goes wrong during the compilation step of the export wizard if that option is not applied.)

  I used Java 11.0.1 and Eclipse SimRel 2018-09 (plus Java11 support plugin)
