Public Note
AntでEclipseで作ったプロジェクトのビルドファイルを書いていて、いままでのビルド系の記事をまとめて見ることにした。
自分は実行可能JarをAntで作っていて、依存ライブラリのコピーが必要なことを忘れていた。
newmasterというブランチを作ったの忘れていた。
これを開発の更新していたら、ビルド成功したので、masterにしたいが、どうすればいいのだろう。
マージすればいいようだが、もっている本だと、Linuxで使えないソフト使っているように見える。
適当にいじっていたら大失敗。newmasterにmasterを取り込んでしまった。
しかもブランチエクリプスで変えたら、ブランチ戻れなくなったよ。ｏrz。
たぶん revertコマンドうまくいけば戻せると思うだけど。

revert できない。
結局、ローカルのバックアップをEclipseに戻して、別ブランチにコミット、プッシュした。
.metadataやら.gitディレクトリがそこにあって、イグノアファイルに書いておいた。
Repository https://github.com/iamaturtle113/jaydle-project warning: GH001: Large files detected. You may want to try Git Large File Storage - https://git-lfs.github.com.
こんな警告がでた。
マージして、Eclipseのプロジェクトまで壊れたので、やばかったな。
まえのプッシュも古くて、元に戻しても、とても古いファイルが復旧されていただろう。
エクリプスのプロジェクトファイルも壊れて、開けなくなっていた。
ローカルにバックアップ取っておいてよかった。でないとプルして整理しなきゃいけなかったようだし。
で、ブランチを整理しないと。clean_antbuildをｍａｓｔｅｒにしよう。
久しぶりにUbuntuのEclipse使ったら、プロジェクトに赤いビックリマーク付いているものばかりで、プログラムが走らない。
Error: Could not find or load main class org.eclipsebook.ch05.Ch05_02
というエラーでる。
しかもコンソールも表示できなくなっていたし。そっちはこちらに書いた。
このビックリマークの意味なんなんだろう。
このlaunchファイル消すのためしたけど、効果なかった。
なんかWorkspace、ごちゃごちゃしている。
ビックリマークの意味調べてみた。

どうやら、jarが見つからなかったようだ。
プロジェクトを右クリック、ビルドパスから設定して直った。
resourceフォルダに依存jarを入れていて、それをｓｒｃディレクトリに入れていたのが原因だったよう。
それをプロジェクト直下に置いたら、見つけられるようになった。
今度はAntのビルドが通らない。

いろいろ格闘した結果、できた。

外部ツールから”「JRE」タブにて「ワークスペースと同じJREで実行」を選択する。”ということでした。
たしかに前もこれやったのにな。
ant用のかな、ランのアイコンの中では一番右のものを右クリックで、External Tools Configurations
絶対前もやったよ。

This script wasn’t enough.
maybe classpath problem.
compile error cause of dependency class files.
[javac]warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
Add
<javac srcdir=”${src}” destdir=”${bin}” classpathref=”classpath” includeantruntime=”false>
solve this.
Below is a main error
error: cannot find symbol
Next
Error: Could not find or load main class jaydle.Main
occurred. This time Project > Clean solved this.
deleting launch configure files aren’t effective.
It seems my ant build.xml file collapsing the project file or classpath file.
This is being cause of this error.
When I checked .classpath file when Error: Could not find or load main class occurred,
lib, resource around naming is the cause.

Realized it’s all about java.awt.Event.ActionListener
eclipse compiler error output -> show view -> problems
This wasn’t useful.
How to see compiler error output??
And how to recompile with -Xdiags:verbose to get full output?
Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output
from
https://stackoverflow.com/questions/4597968/how-to-recompile-with-xlintunchecked-in-ant-build-task
<compilerarg value="-Xdiags:verbose"/>It worked but no clue to solve

It’s all
src/jaydle/JaydlePrototype.java and
“cannot find symbol” and “incompatible types” errors.
error: cannot find symbol
[javac] class MenuListenerSaveDir implements ActionListener
error: incompatible types: JaydlePrototype.MenuListenerSaveDir cannot be converted to ActionListener
[javac] menuItem1.addActionListener(new MenuListenerSaveDir());
After this, I tried other projects, and had no problems so maybe import statements errors.
I’m trying to write my java build program.
Yes, but “Navigator” displays it. Only package folder(s).

And exported for other pc environment…
So if you will, take responsibillity…
Today I installed Eclipse Oxygen to clean installed Windows 7 on NEC LaVie laptop which I call “dee-jay” because this is for Traktor DJ.
And when lauching Eclipse it said like “Need newer JDK than 1.6”.
So I downloaded the source from here.
https://jdk.java.net/java-se-ri/8
Here I heard “Windows i586” for the first time.
But it was not problem so. Just CPU architecture (guess old).
After downloaded the zip extracted to “Program Files” directory.
And added the path to “Environmental Variables”.
But it kept using 1.6 JDK.
Configuring “JAVA_HOME” environment variable was not effective too.
Finally I uninstalled old “Oracle JDK 1.6” from the “Control Panel” > “Uninstall Softwares”.
This was great. 1.6 jdk was at “System32” directory whereis high priorities.
I used
start — this start programs in the search path.
path — this displays path variable values.
(setx path “%path%; this is useful to set path variable)
commands on Command prompt.
And now fighting to Clone git repository on eclipse LoL.
To begin from the cause and solve method…
serObj=load("jaydle.ser");
This statement causes all errors which eclipse said “cannot be resolved to a type” or something like that error.
It highlighted as red circle X, and the others are red light objects.
It said all of my original objects in the class are “cannot be resolved to a type” or something wrong.
From terminal (command line), I tried to compile and error occurred, it pointed
masa@em-p:~/Public/git/jaydle-project/jaydle-project$ javac src/jaydle/JaydlePrototype.java
src/jaydle/JaydlePrototype.java:61: error: <identifier> expected
serObj=load("jaydle.ser");
all of errors disappeared and Mose came. lol.
Eclipse configuration is hard. And error detective system this case reverse effected….
See you!
